Solution
The correct option is C 3
Barr body is a mass of condensed sex chromatin in the nuclei of normal female somatic cells. Its compact appearance is due to its inactivity.
Thus Barr body represents the inactivated X-chromosomes and the number of Barr bodies in a cell is one less than the total number of X-chromosomes in it.
Therefore, for this question, the number of Barr bodies seen is 3.
