Dear student,
Please find below the answer:
The correct option is (c).
In a healthy individual, there are two normal heart sounds called lub and dub . Lub is the first heart sound. It is associated with the closure of the tricuspid and bicuspid valves at the beginning of systole. The second heart sound dub is associated with the closure of the semilunar valves at the beginning of diastole. The time duration between heart sound 'dub' to 'lub' is 0.5 seconds.
Hope this information clears your doubt.
Regards.
