I think the answer is d not quite sure tho
The process of DNA replication occurs just before S phase. In the interphase, the cell has growth and replication of DNA is getting made. In the G1 phase, there is the growth, (G1-checkpoint - cell size, growth, environment shows cell is ready to start replicating DNA. S phase- DNA is replicated.

"Skeletal muscle, also called voluntary muscle, in vertebrates, most common of the three types of muscle in the body. Skeletal muscles are attached to bones by tendons, and they produce all the movements of body parts in relation to each other. Unlike smooth muscle and cardiac muscle, skeletal muscle is under voluntary control. Similar to cardiac muscle, however, skeletal muscle is striated; its long, thin, multinucleated fibres are crossed with a regular pattern of fine red and white lines, giving the muscle a distinctive appearance. Skeletal muscle fibres are bound together by connective tissue and communicate with nerves and blood vessels."
