Solution

The correct option is C Semilunar valve at the base of aorta closes
During each cardiac cycle two prominent sounds are produced, which can be easily heard through a stethoscope. The first heart sound (lub) is associated with the closure of the tricuspid and bicuspid valves, whereas the second heart sound (dub or dup) is associated with the closure of the semilunar valves. These sounds are of clinical diagnostic significance.
