Solution

The correct option is B Which has a chromatin body attached to the secondary constriction
Satellite chromosomes are chromosomes that contain secondary constructs that serve as identifying markers. Besides the centromere, one or more secondary constrictions can also be observed in some chromosomes at metaphase.
So, the correct option is A.
