The correct answer is:
$(C),(B),(A),(D),(E)$
In angiosperms the correct sequence of events in formation of female gametophyte in the ovule is

- One remains functional and three degenerate.(B)
- 3 successive free nuclear divisions in functional megaspore take place.(A)
- Migration of 3 nuclei towards each pole.(D)
- Formation of wall resulting in seven celled embryo sac.(E)
