• C. Telocentric Chromosome.
• D. None of these.

Answer 1

The correct option is A

Acentric Chromosome.

The correct option is A.

Explanation of correct option:

1. Acentric chromosomes lack centromeres as a result spinal fibers are not attached to them.
2. Hence, they are not able to move towards the pole and are lost during cell division.

Explanation of incorrect options:

Option B:

1. Polycentric chromosomes have multiple centromeres.
2. They cannot separate during anaphase resulting in cell death.

Option C:

1. In the telocentric chromosome, the centromere is present at the end of the chromosome.
