Options
- AA-IV, B-I, C-III, D-II
- BA-III, B-IV, C-I, D-II
- CA-III, B-I, C-II, D-IV
- DA-III, B-I, C-IV, D-II
Correct answer
D. A-III, B-I, C-IV, D-II
Step-by-step solution
Antipodal cells are part of the female gametophyte and are haploid ( n ). The central cell, before fertilization, contains two polar nuclei and its genetic constitution is represented as n+n . The zygote is formed by syngamy (fusion of a male gamete with the egg cell) and is diploid ( 2n ). The primary endosperm cell is formed by triple fusion (fusion of a male gamete with two polar nuclei) and is triploid ( 3n ). Therefore, the correct matching is A-III, B-I, C-IV, D-II. Answer: A-III, B-I, C-IV, D-II
