Accepted Answer

B. Inhibiting phosphodiesterase-5 (PDE5) — Sildenafil is a selective inhibitor of phosphodiesterase-5 (PDE5), an enzyme responsible for the degradation of cyclic guanosine monophosphate (cGMP) in the corpus cavernosum. By inhibiting PDE5, sildenafil increases cGMP levels, leading to smooth muscle relaxation and enhanced blood flow into the penis, facilitating an erection in response to sexual stimulation.
