Answer

Brief Explanation:

Muscle contraction starts at the myofibril level. Myofibrils contain sarcomeres which are the basic contractile units. When sarcomeres contract, it leads to the contraction of the whole muscle. Muscle fibers are made up of myofibrils. The myoneural junction is the site of communication between a nerve and a muscle. Tendons attach muscle to bone and fascicles are bundles of muscle fibers.

Answer:

A. myofibril
