Males can never be carriers. They have single X and other Y chromosome. In X linked inheritance, the genes are present on the nonhomologous region of X chromosome. Males do not have other X and hence if the genes are present on his X chromosome, they will not be suppressed in them. The Y chromosome does not have dominant gene to hide this expression as there is no homolorous region too. But in case of females, there are double X chromosomes and hence if X-linked gene is recessive, the other X can hide the expression of such X-linked gene.
Thus she becomes a carrier without showing any physical characters. She is physically normal and does not suffer from such Xlinked recessive disorder. Thus, Madhav will get his answer wrong due to incorrect concept.
