The correct Answer is:
A
In pigeons, ZW-ZZ type of sex determination mechanism is found. In this type the male has two homomorphic sex chromosomes (ZZ) and is homogametic, and the female has two hetermorphic sex chromosomes (ZW) and is heterogametic. There are, thus two types of eggs : with Z and with W and only one type of sperms, i.e, each with Z.
