Solution

The correct option is B Skeletal muscle fibre
Sarcolemma is found over skeletal muscle fibre. The sarcolemma is the cell membrane of a striated muscle fiber cell. It consists of a plasma membrane, which is a lipid bilayer, and an outer coat consisting of a thin layer of polysaccharide material (glycocalyx) that contacts the basement membrane, which contains numerous thin collagen fibrils and specialized proteins such as laminin that provide a scaffold for the muscle fiber to adhere to.
The sarcolemma generally maintains the same function in muscle cells as the plasma membrane does in other eukaryotic cells.
Therefore, the correct answer is option B.
