Solution
The correct option is D Magnesium ion
Sarcoplasmic reticulum combine with troponin and calcium ions are released. Binding of calcium ions shifts the tropomyosin from their position to expose myosin binding sites. Binding of myosin heads to actin filament is followed by power stroke that makes the actin filaments to move past myosin filament. This shortens the sarcomere causing muscle contraction. Thus, the correct answer is option D.
