Answer 1

The correct option is A

Skeletal muscle

Skeletal muscle is striated, voluntary, shaped like long fibers, multinucleated. Smooth muscle is nonstriated, involuntary, shaped like almonds (tapered ends), one nucleus per cell. Cardiac muscle is striated, involuntary, branched, shape like fibers cross-linked to one another, typically one nucleus per cell.
