Detailed Solution

Both (A) and (R) are false.

FSH (Follicle-Stimulating Hormone) primarily binds to membrane-bound receptors on the surface of target cells, initiating intracellular signaling pathways without entering the cell itself. FSH, being a protein hormone, cannot traverse the lipid-based plasma membrane due to its hydrophilic nature and larger molecular size. Instead, it binds to specific membrane-bound receptors to exert its effects on target cells.
