NH-148A is the shortest National Highway in Haryana, with a length of just 6 km. It is located in the southern part of the state and connects major road routes in that region. In contrast, other highways like NH-9 (285.9 km) and NH-1 (now NH-44, much longer) are considerably longer. NH-148A plays a localized role in connecting smaller areas within Haryana, unlike the other national highways, which serve as major inter-state corridors.

NH-148A is the shortest National Highway in Haryana, measuring only 6 km. This makes it a relatively small and localized highway compared to other National Highways in the state, which are much longer. It connects certain smaller towns or road routes in the southern part of Haryana. Although short in length, NH-148A serves its purpose by connecting local regions and enabling better movement of people and goods within that area.

The other options are significantly longer highways:

• NH-9 has a length of 285.9 km and passes through six districts in Haryana.
• NH-10 (also known as NH-44) is much longer and connects important regions including Delhi and Punjab.
• NH-1 (now NH-44) was historically a key part of the Grand Trunk Road, extending far beyond Haryana, covering long distances across multiple states.

Thus, NH-148A is the shortest, with a length of only 6 km, making it quite a minor highway compared to the major ones listed in the options.

Hence option C is correct.

The Haryana Public Works Department (PWD) is the government department responsible for the development, construction, and maintenance of public infrastructure, including roads, bridges, and buildings, in the state of Haryana. The department plays a crucial role in planning, designing, and executing various projects related to road infrastructure to ensure the smooth movement of people and goods within the state.

Hence, option A is correct.

NH 781: This highway passes through Rewari. It connects different towns in Haryana, with Rewari being one of the key locations on this route. So, the correct match is 3.

NH 71 A: This highway passes through Rohtak, a major city in Haryana. NH 71 A connects major areas and passes through Rohtak as an important town on the route. Hence, the match is 4.

NH 73: This highway passes through Roorkee, a city in Uttarakhand known for being on the route of NH 73. This makes the correct match 1.

NH 72: This highway passes through Ambala, a prominent city in Haryana and Punjab. It is well-connected by NH 72. Therefore, the correct match is 2.
 

A. NH 781

• NH 781 is a National Highway that passes through Rewari in Haryana. This highway connects Rewari to various towns, including those in Rajasthan. Rewari is one of the significant towns along NH 781, which is why the correct match for NH 781 is Rewari (Option 3).

B. NH 71 A

• NH 71 A passes through Rohtak, which is an important city in Haryana. This highway connects Delhi with Rohtak, and Rohtak is a prominent landmark on this route. Hence, the correct match for NH 71 A is Rohtak (Option 4).

C. NH 73

• NH 73 passes through Roorkee, a city located in Uttarakhand. NH 73 is a key highway connecting Roorkee to other parts of the region, including parts of Uttar Pradesh. Roorkee is a significant passing point for NH 73, so the correct match is Roorkee (Option 1).

D. NH 72

• NH 72 passes through Ambala, which is located in Haryana. Ambala is a major city that serves as a junction for several important roads, including NH 72. This highway connects Ambala with several towns in the region, making Ambala a significant point on NH 72. Therefore, the correct match for NH 72 is Ambala (Option 2).

Summary of Correct Matches:

• A (NH 781) → 3 (Rewari)
• B (NH 71 A) → 4 (Rohtak)
• C (NH 73) → 1 (Roorkee)
• D (NH 72) → 2 (Ambala)

So, the final matching answer is 3 4 1 2.

Hence Option C Is Correct.
