Low level languages have the advantage that they can be written easily to take advantage of any distinctive features in the architecture of the central processing unit (CPU), which is the "brain" of a computer. Thus, a program written in a low-level language can be extremely efficient, making optimum use of both computer memory and processing time.

• However, to write a high-level program, it takes a substantial amount of time as well as clear understanding of the inner workings of the processor itself.
• Therefore, low-level programming is typically used only for very small programs or for segments of code that are highly critical and must run as efficiently as possible.Low language is considered to be closer to the computer.
• The Low-level language is a programming language that provides no abstraction from the hardware,and it is represented in 0 or 1 forms,which are the machine instruction. we can say that these programming languages are more difficult to understand . It is design to operate and handle the entire instructions set of a computer system directly which are generally used to write the system software.

There are two types of Low level languages:

1. Machine Language

2. Assembly Language     

In this Question:

How many types of Low Level Language ?

The answer is 2.

Hence the option B is correct.

Advantages of Low Level Language:

• 1. Programs developed using Low level Languages are fast and efficient.

• 2. There is no need of any compiler or interpreters to translate the source code to Machine code.Thus,cuts the compilation and interpretation time.

• 3. It can directly communicate with Hardware devices.

Disadvantages of Low Level Language:

There are two types of Low Level languages:

1. Machine Language

2. Assembly Language                       

In this Question:

Machine Language and Assembly Language are types of _______________

The answer is Low Level Language.

Hence the option A is correct.

Advantages of Low-Level Language:

• 1. Programs developed using Low level Languages are fast and efficient.
• 2. There is no need of any compiler or interpreters to translate the source code to Machine code. Thus, cuts the compilation and interpretation time.
• 3. It can directly communicate with Hardware devices.

Disadvantages of Low-Level Language:​​​​​​​

• 1. It is difficult to develop, debug and maintain.
• 2. Programmer must have knowledge of the computer architecture of particular machine, for programming in low level language.

There are two types of Low-level languages:

1. Machine Language

2. Assembly Language       

In the Question:

Which of the following statement is Advantage of Low Level Language?

(i) Programs developed using Low level Languages are fast and efficient.

(ii) There is no need of any compiler or interpreters to translate the source code to Machine code

(iii) Programmer must have knowledge of the computer architecture of particular machine.

The Answer is both i and ii.

Hence the Option C is Correct.
