Dear Student,

Semilunar valve close after the ventricles relax, arterial pressure exceeds ventricular pressure. it close after ventricular systole (.3 second of cardiac cycle)
AV valves close at end of ventricular diastole (.8 second of cardiac cycle)
​​the difference between them is 0.5 sec.
so correct option is 2 .
