Solution

The correct option is B Semilunar valves
The closing of different valves in the heart produces different characteristic sound commonly known as the lub-dub sounds. The lub sound is the first sound of the heart. The dub sound is the second sound of the heart that is produced by the closing of the semilunar valves in the heart.
Thus, the correct answer is 'Semilunar valves.'
