Correct answer: (a) 
Solution: Quiescence is a condition in which seeds do not germinate due to unfavourable environmental conditions. When favrouable conditions return, the seed will germinate. Seeds of some plants do not germinate even under favourable conditions. This is called as dormancy. It is under endogenous control.
Thus, the correct answer is 'Dormancy'.
