Answer:

B.) Skeletal muscles

Explanation:

Skeletal muscles are also known as striped or striated or voluntary muscles. These muscles are attached to the skeleton. These muscles are present in bundles. Each muscle fibre is an elongated cell having large number of myofibrils in its cytoplasm. Each myofibril has dark and light bands on it. The dark bands are A-bands or aniso-tropic bands and the light bands are I-bands or isotropic bands.
