In bacteria,fungi,and lower plants,various thick-walled $A$ are formed,which help them to survive $B$ conditions; these germinate on the availability of a suitable environment. In higher plants,$C$ and some other vegetative reproductive structures serve as means to tide over periods of stress besides helping in dispersal; they germinate to form new plants under favourable moisture and temperature conditions. Choose the correct option for $A, B$,and $C$.
