The correct option is B Meromyosin
Contractile proteins are involved in contraction and relaxation of skeletal muscles. Myosin and actin are the contractile proteins. The myosin filament or the thick filament is made of heavy meromyosin and light meromyosin. The actin filament or the thin filament is made of F-actin, troponin, and tropomyosin.
