उत्तर

A V-shaped chromosome is metacentric.

Explanation:

Metacentric chromosomes have their centromere positioned exactly in the middle, dividing the chromosome into two equal arms. During the anaphase stage of cell division, as spindle fibres pull the chromosome toward the pole from this central point, both arms trail behind equally. This symmetrical movement forces the chromosome to assume a distinct V-shaped appearance.
