The district of Mewat had the highest sex ratio in both rural and urban areas in Haryana according to the 2011 Census. The district reported a sex ratio of 907 females per 1000 males, which was the highest in the state for both rural and urban areas. Mewat stands out not only for its overall sex ratio but also for the fact that it maintained this top rank across both these categories, suggesting that gender balance efforts may have been more effective or that traditional gender biases in the region were less pronounced compared to other districts.

In Mewat, the rural sex ratio was equally notable, as it was also reported at 907 females per 1000 males, which reflects a significant achievement for a rural district where gender imbalances are often more pronounced due to cultural factors and socio-economic conditions. The district’s urban sex ratio also mirrored this figure, maintaining the highest sex ratio across urban areas in Haryana in 2011. This indicates that gender equality measures in Mewat may have been more successful than in other parts of the state, where urban areas often show lower sex ratios due to urbanization, changing lifestyles, and higher instances of sex-selective practices.

The higher sex ratio in Mewat can be seen as a result of various factors, including governmental interventions, community efforts, and awareness programs aimed at improving the status of girls and women. Over the years, the district has witnessed initiatives focusing on promoting female education, addressing gender-based violence, and reducing the preference for male children. These efforts, combined with social reforms and awareness campaigns, may have contributed to Mewat's relatively balanced sex ratio, which is an encouraging sign in a state that has historically struggled with gender imbalances.

Hence Option A is Correct.

The sex ratio of a region is the number of females per thousand males. According to the Census of 2011, the sex ratio of Haryana was recorded at 879 females per 1000 males. This figure was an improvement from the 2001 Census, when Haryana had a sex ratio of 861 females per 1000 males. Despite the improvement, Haryana's sex ratio in 2011 remained lower than the national average of 943 females per 1000 males, reflecting ongoing gender imbalances in the state.

Haryana has long struggled with skewed sex ratios, a situation often attributed to a combination of cultural, social, and economic factors. The state's historical preference for male children, coupled with practices such as sex-selective abortions and neglect of female children, have contributed to these disparities. However, the slight increase in the 2011 Census suggests that efforts to address these issues—such as government policies to discourage sex-selective practices and promote the welfare of girls—may have had some positive impact over time.

Despite the improvement, Haryana still faced challenges with its sex ratio in specific districts. For example, districts like Gurgaon and Sonipat recorded some of the lowest sex ratios in the state, while Mewat and Fatehabad saw higher ratios. The state also showed significant urban-rural differences: the rural sex ratio was higher than the urban ratio, with districts like Mewat and Rewari leading the rural sex ratio, and urban areas like Gurgaon showing particularly low numbers. These disparities indicate the complex and multifaceted nature of gender imbalances in the state.

Hence Option B is Correct.

The sex-ratio of Haryana state increased from 861 to 879 as per 2011 census (gain of 18 points) with increase from 866 in rural areas to 882 (gain of 16 points) and in urban from 847 to 873 (gain of 26 points). Highest sex ratio has been reported in Mewat (907) followed by Fatehabad (902) and Rewari (898).

Hence, option B is correct.
