Easy

A

It is formed in diplotene of prophase I of meiosis I
B

It is chromosome with two arms seen in leptotene of prophase I of meiosis I
C

One bivalent consists of four homologous chromosomes and formed in zygotene of prophase I of meiosis I
D

It has two homologous chromosomes joined by synaptonemal complex and formed in zygotene of prophase I of meiosis I
