The synaptonemal complex is first seen in ...........

Assertion : Meiosis $II$ is known as equational or homotypic division.
Reason : Meiosis $II$ produces the same number of chromosomes in the daughter cells as in the parent cell.

Match the stages of prophase $I$ given in Column-$I$ with their features in Column-$II$ and choose the correct options from the choices given below:

Column $I$	Column $II$
$A$. Leptotene	$i$. Chromosomes visible under light microscope
$B$. Zygotene	$ii$. Chromosomes start pairing together
$C$. Pachytene	$iii$. Exchange of genetic materials between non-sister chromatids of the homologous chromosomes.
$D$. Diplotene	$iv$. Dissolution of synaptonemal complex
$E$. Diakinesis	$v$. Terminalisation of chiasmata

In which of the following stages are the chromosomes seen as unclear or thread-like?

Meiosis-$II$ is?

$A$: Synaptonemal complex develops between two synapsed homologous chromosomes.
$R$: Mitosis cannot be completed without the synaptonemal complex.
