Correct answer: A

Barr body is a mass of condensed sex chromatin in the nuclei of normal female somatic cells due to inactive X chromosome. Whenever the number of X-chromosomes is two or more than two, the number of barr bodies is one less than the number of X-chromosomes. Therefore, the number of barr bodies in XXXX female is three.
