Answer 1

The Correct Option is D

Ovum (B): This refers to the unfertilized egg cell. Morula (D): This is a solid mass of cells that develops after successive mitotic cell divisions. Blastocyst (G): This is a hollow ball of cells observed in early embryonic stages, which then attaches to the uterine lining.
