Option C, striated muscles

Explanation:

Striated muscle is of two types  

a)Skeletal muscle  - These muscles are attached to the bones

b)Cardiac muscle - These muscles are attached on the walls of the heart.

These two muscles have a striated appearance due to closely packed myofibrils and are sometime also referred as striated tissue. There is a layer of epimysium within its fascia that separates the muscles from the nearby structures.  

Striated muscles are attached to the bones by a network of tendons and allows voluntary bone movement
