Options

• Smooth muscles contract and pull the tendons to move the bones

• Skeletal muscles contract and pull the ligament to move the bones

• Skeletal muscles contract and pull the tendon to move the bones

Answer 1

Skeletal muscles contract and pull the tendon to move the bones

Explanation - 

Skeletal muscles or striated muscles are found in the body wall and the limbs (biceps and triceps of arms, legs). The contraction and relaxation of these muscles are under the control of the organism, so they are also called voluntary muscles. These are attached to the bones by tendons. When they contract, they pull the tendon to move the bones and help in the movement of limbs.
