The correct answer is: absence of one X -chromosome
Option (a) is incorrect/odd with respect to human male because the male karyotype has $44+\mathrm{XY}$ chromosomes. This means single X -chromosome is present with one Y-chromosomes. Barr body is an additional X-chromosome found in female somatic cells.
