Correct Answer : A.
Satellite is a small chromosomal segment separated from the main body of the chromosome by a secondary constriction. In humans it is usually associated with the short arm of an acrocentric chromosome. They play a vital role in the formation of the nucleolus after cell division. In humans, chromosomes number 13, 14, 15, 21 and 22 are examples of SAT (satelite) chromosomes.
