Quizplus · Accepted Answer

The correct sequence in the development of gymnosperm megasporangium is as follows: 
1) Megaspore 
2) Female gametophyte 
3) Egg cell 
4) Sporophyte embryo. 
If fertilization occurs, the sperm will travel down the pollen tube and fertilize the egg cell within the female gametophyte, which will then develop into a sporophyte embryo. Thus, the correct sequence is 4→2→3→1. Choice (B) is the only one that has this sequence, making it the correct answer.
