Solution

The correct option is C One X chromosome only
Unfertilized egg is female gamete which is haploid. It contains X chromosome. The sperm contains either an X or a Y chromosome. A male child (XY) is produced if the sperm containing a Y chromosome fuses with the egg. If the sperm containing an X chromosome fuses with the egg then a female child (XX) is produced.
