The longest phase of meiosis is

Choose the correct pair:

$S -$ Statement: Recombination nodules are visible during the diplotene stage.
$R -$ Reason: Synapsis occurs during the zygotene stage.

The various stages of meiosis are given in Column-$I$. Match them with the characteristics of the various stages of meiosis in Column-$II$ and select the correct option using the codes given below.

Column-$I$	Column-$II$
$A$. Pachytene	$i$. Pairing of homologous chromosomes
$B$. Metaphase-$I$	$ii$. Terminalization of chiasmata
$C$. Diakinesis	$iii$. Crossing over occurs
$D$. Zygotene	$iv$. Alignment at the equatorial plate

The beginning of which stage of prophase is marked by complete terminalisation of chiasmata and inhibition of $RNA$ synthesis?

The process of synapsis is observed in which phase?
