Answer:
Option-B
Explanation:
The excitability is the property of cell which allows the cellular response to the stimulus which comes as an electrical impulse.
When the muscle cell or tissue is said excitable it means that the muscle tissue or cell response to the electrical impulses.
In the given question, the electrical impulse travels down the motor neurons and reaches the muscle. In the muscle, T-tubules transfer the impulse to the sarcolemma where the calcium is stored. As soon as the impulse reaches the sarcolemma, the calcium is released which can bind to the troponin molecule make the myosin binding site available and the cross-bridge is formed as a result of which the muscle can contract.
Thus, Option-B is correct.
