Complete Answer:
The word muscles is derived from a latin word “musculus” which means little mouse. There are basically three types of muscles,
(I) Smooth muscles - These are striated muscles which are found in almost all the organs systems and they help in production of connective tissue proteins such as elastin and collagen.
(II) Skeletal muscles - These muscles are found attached to the bones in the body and help in functioning of different body parts. They help in maintaining the body posture.
(III) Cardiac muscles - These muscles are found in the walls of the heart and are responsible for heart functions like - circulation and pumping of blood throughout the body.

In the human body there are more than 600 muscles. Muscles are responsible for 40-50 percent of the total body weight in humans. Muscles are attached to various blood vessels, bones, internal organs, etc.
As the number of muscles in the human body is more than 600, option A, C and D are incorrect.

- They help in movement of the body and also maintain the body posture.
- They help in movement of internal organs like the movement of food in the gastrointestinal tract and contraction of the heart.
