The correct statement is: C.Ligands bind to receptors to initiate cell communication.

In cell communication, ligands are signaling molecules (such as hormones, neurotransmitters, or growth factors) that bind to specific receptors on the surface of or inside target cells. This binding triggers a series of intracellular signaling events that result in a cellular response.

Here's a breakdown of the other options:

A."Ligands repel receptors to inhibit cell communication": This is incorrect. Ligands typically bind to receptors to initiate communication, not...
