Give the name of the subunits of Troponin.

(N/A) Troponin is a regulatory protein complex associated with the actin filament in muscle fibers. It consists of three distinct subunits:
$(a)$ Troponin $I$ $(T_pI)$: This subunit inhibits the interaction between actin and myosin.
$(b)$ Troponin $T$ $(T_pT)$: This subunit binds to tropomyosin,anchoring the troponin complex to the tropomyosin strand.
$(c)$ Troponin $C$ $(T_pC)$: This subunit acts as a binding site for calcium ions $(Ca^{2+})$,which triggers the contraction process.
