Solution
The correct option is C Acrocentric
1) An acentric fragment is a segment of a chromosome that lacks a centromere.
2) Acrocentric chromosomes have a centromere which is severely offset from the center (i.e sub-terminal) leading to one very long and one very short section.
3) Metacentric chromosomes have the centromere in the center, such that both sections are of equal length.
4) Telocentric chromosomes have the centromere at the very end of the chromosome.
