Answer 1

The correct option is A Metacentric

Based on the position of the centromere, chromosomes are categorised as metacentric, submetacentric, acrocentric and telocentric.

Metacentric have centromere in the middle of the chromosome with two equal arms of the chromosomes.

Sub-metacentric has sub-terminal centromere with one shorter arm and one longer arm.

Acrocentric have centromere close to its end forming one extremely short and one very long arm.

Telocentric have terminal centromere.

Thus, the correct answer is option A.
