The correct answer is

tricuspid valve

Anatomical Breakdown

The opening between the right atrium and the right ventricle is guarded by the tricuspid valve (composed of three muscular flaps or cusps).

For comparison, the opening between the left atrium and the left ventricle is guarded by the bicuspid (mitral) valve.

Correct Answer

Option 4 (tricuspid valve)
