Solution
The correct option is A Sacroplasmic reticulum Answer is option C i.e. "Sacroplasmic reticulum" Neurotransmitter acetylcholine generates an action potential in the sarcolemma causing the release of calcium ions into the sarcoplasm from the sarcoplasmic reticulum. When Ca++ level increases it leads to the binding of calcium with a sub-unit of troponin on actin(thin) filaments and thereby activating the movement.
