Explanation:

The sound of a heartbeat is produced by the closure of heart valves. The first heart sound is generated by the closure of the bicuspid and tricuspid valves, while the second heart sound is generated by the closure of the aortic and pulmonary valves.

- First heart sound: The first heart sound is a low-frequency sound that is longer in duration. It is produced by the closure of the bicuspid and tricuspid valves, which occurs at the beginning of systole when the ventricles contract. This sound is also known as S1.

- Second heart sound: The second heart sound is a higher frequency sound that is shorter in duration. It is produced by the closure of the aortic and pulmonary valves, which occurs at the end of systole when the ventricles relax. This sound is also known as S2.

Therefore, option B is the correct answer as it states that the first sound of a heart beat is produced by the closing of the bicuspid and tricuspid valves.
