(C) The mechanism of muscle contraction is explained by the Sliding Filament Theory.According to this theory,muscle contraction occurs when thin filaments (actin) slide over the thick filaments (myosin).This process is initiated by a signal sent by the central nervous system via a motor neuron.As the thin filaments slide over the thick filaments,the $Z$-lines attached to the actin filaments are pulled inwards,causing the shortening of the sarcomere,which results in muscle contraction.
