Solution

The correct option is A
Smooth muscles

Muscles are also called myocytes. Uni-nucleate and un-branched myocytes are present in smooth muscles. Skeletal muscle cells are multinucleated, because they consists of several cells that are fused together. Cardiac muscle is present, only in heart. Like skeletal muscle, it also possess cross striations in its cells, but cardiac muscle has a single, centrally-located nucleus; it's muscle branches in many directions.
