Answer

Correct answer: a) Both A and R are true, and R is the correct explanation of A

Both statements are true, and R correctly explains A: sildenafil inhibits phosphodiesterase type 5, preventing breakdown of cGMP; the resulting cGMP accumulation potentiates nitric oxide-mediated smooth muscle relaxation in the corpus cavernosum, enhancing penile blood flow and erection — the direct mechanistic basis for its use in erectile dysfunction.
