Solution
The correct option is B Myosin
Muscle contraction thus results from an interaction between the actin and myosin filaments that generates their movement relative to one another.
The molecular basis for this interaction is the binding of myosin to actin filaments, allowing myosin to function as a motor that drives filament sliding. Hence, The binding of troponin to calcium in muscle cells exposes the binding site of Myosin.
