• B. apomixis
• C. diplospory
• D. polyembryony

Answer 1

The correct option is A apospory

Apomixis is a type of asexual reproduction in plants which occurs without fertilisation.

Apospory is a type of apomixis in which the formation of embryo sac occurs from diploid vegetative structure (nucellus or integument) without meiosis.

Diplospory is when the embryo sac is derived from the megaspore mother cell directly.

Polyembryony refers to the occurrence of more than one embryo in a seed.
