Solution

The correct options are
B Choanocytes
C Archaeocytes
Sponges or Poriferans are mostly Hermaphrodite (Monoecious), whereas a few species are known to be Unisexual (Dioecious). But in all sponges, sexual reproduction initiates through cross-fertilization between gametes. However, discrete reproductive organs i.e. gonads are lacking in sponges.
So, the gametes of sponges are not produced by gonads. Instead, the gametes (sperms and ova) are derived from some special types of cells, known as the Choanocytes and the Archaeocytes.

Q. X and Y are two human beings. The organ A in the reproductive system of X releases a mature gamete B once a month which goes into a tube-like structure C through a funnel-like opening. The organ D in the reproductive system of Y makes and releases gametes E which pass through a duct F and are introduced by an organ of Y, into the body of X. B and E fuse together in C to form a new cell G. The cell G divides repeatedly to form a ball of cells H which gets embedded in the lining of organ I of reproductive system of X where it grows and develops into a baby.
