Correct answer

D. (A) is correct but (R) is not correct

Step-by-step solution

The bicuspid valve, also known as the mitral valve, guards the opening between the left atrium and the left ventricle. Hence, the Assertion is correct. The mitral valve is formed of two muscular flaps or cusps, not three. The valve formed of three muscular flaps is the tricuspid valve, which guards the opening between the right atrium and the right ventricle. Hence, the Reason is incorrect.
