Solution

The correct option is B A-(ii),B-(iv),C-(i),D-(iii)
Anaphase is a stage where the chromosomes split from the middle and two chromatin get separate and both the chromatids move toward opposite poles due to a repulsive force which is known as an aphasic moment.
The different shapes of chromosome become evident during chromosome movement that is metacentric, acrocentric et cetera. If the chromosome is V-shaped at anaphase then it would be metacentric because it is from the exact centre of the centromere.
If it is L shaped at anaphase then it will be submetacentric because one arm would be smaller than the other arm. If it is J shaped then it is acrocentric chromosome because it is on one end of the chromosome and if it is I shaped then it is telocentric
So, the correct option is 'A-(ii),B-(iv),C-(i),D-(iii)'
