Solution

The correct answer is "option C"

(a) Meta centric
chromosome - Centromere is at the middle. Forms two
equal arms of the chromosome

(b) Acrocentric
chromosome - Position of centromer is close to the end –
forms one very short arm and one very long arm.

Sub meta centric chromosome - Position of centromer is slightly away from the middle, as a result
– one arm is shorter and one arm is onger.

d. Telocentric
chromosome - Centromere is located terminal end.
