The male sex gametes possess X and Y chromosomes, and the female sex gametes possess two X chromosomes. The sex of the child depends on the gamete of the male which fuses with the female. If the X gamete fuses, the zygote formed has the XX chromosomes which form a girl child whereas, the male child is formed by the zygote with the XY chromosome content. So, the correct answer is option D.
