The period between the end of one heartbeat to the end of next heartbeat is called cardiac cycle. Cardiac cycle is formed of three phases.
Atrial systole, ventricular systole and joint diastole. During ventricular systole closing of Auriculo ventricular (AV) valves at the start of ventricular systole produces first heart sound called 'lubb' or systolic sound.
During joint diastole rapid closure of semilunar valves at the beginning of ventricular diastole produces the second heart sound called 'dup'.

Two distinct sounds can be heard during heart beat with the help of stethoscope. These are 'lub' and 'dup'.
Lub is the first sound which has a low pitch and produced by the closure of tricuspid and bicuspid valves (collectively called atrioventricular valves) at the beginning of ventricular systole. Dup is the second sound which is sharp and has a high pitch. It is produced by closure of semilunar valves by the end of ventricular systole. So, the correct answer is 'Semilunar valves'.
