Solution
The correct option is C Oospore After fertilization, the fertilized egg is called zygote or oospore which develops into an embryo. The oospore divides transversely forming two cells, a terminal cell, and basal cell. The cell towards the micropylar end of the embryo sac is the suspensor cell (i.e., basal cell) and the other one makes to the embryo .cell (i.e., terminal cell). The terminal cell by subsequent divisions gives rise to the embryo while the basal cell contributes to the formation of suspensor.
