Hydra reproduces through

The given figure shows gametes. Select the correct option.

Choose the correct pair:

Match the following columns:

Column-$I$ (Organisms)	Column-$II$ (Chromosome number in gamete)
$P$. Apple	$I$. $12$
$Q$. Rice	$II$. $10$
$R$. Maize	$III$. $190$
$S$. Potato	$IV$. $17$
$T$. Butterfly	$V$. $24$

The processes of gametogenesis and gamete transfer are included in the ......... phase.

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 $C$.
