Specialized plasma membrane surrounding the muscle fiber.
A
Myofibril
B
Myofilament
C
Sarcolemma
D
Sarcomere
Explanation: 

Detailed explanation-1: -The sarcolemma is the plasma membrane of the muscle cell and is surrounded by basement membrane and endomysial connective tissue. The sarcolemma is an excitable membrane and shares many properties with the neuronal cell membrane.

Detailed explanation-2: -The sarcolemma is a specialized cell membrane which surrounds striated muscle fiber cells. Sometimes called the myolemma, the sarcolemma is similar to a typical plasma membrane but has specialized functions for the muscle cell.

Detailed explanation-3: -Across the synaptic cleft from the synaptic end bulb is a specialized region of the muscle fiber sarcolemma known as the motor end plate (postsynaptic membrane). There is one neuromuscular junction associated with each muscle fiber, and it is typically located near the middle of the fiber.

Detailed explanation-4: -The sarcolemma is a specialized membrane which surrounds striated muscle fiber cells.

Detailed explanation-5: -The sarcolemma maintains the intracellular milieu, actively transports substrates into the muscle cell, serves as a docking location for proteins originating in the basement membrane and cytoskeleton, and also transmits neural excitatory impulses that lead to muscle contraction.
