• C. Development of new individual from the union of two sperms
• D. Development of new individual directly without forming an embryo

Answer 1

Answer: (A)

Development of embryo without gametic union

Development of embryo without gametic union is agamospermy. It is a type of apomixis which is a special mechanism to produce seeds without fertilization. It is a form of asexual reproduction that mimics sexual reproduction. In agamospermy, a diploid embryo sac is formed from megaspore mother cell of a nucellar cell which has a diploid egg or oosphere. The diploid egg develops into a diploid embryo. Agamospermy occurs in apple, pear, etc.

Hence, the correct option is A.
