Answer 2

Dear Dhanush,

● Answer -
(a) 88


◆ Explanation -
During meiotic division in angiospermic plants, each megaspore produces 4 dilpoid nuclei (ovules).
Out of these, only 1 matures & rest 3 gets degenerated.

So each meiotic division will effectively produces only 1 viable ovule. Thus 88 meiotic divisions are required to produce 88 viable ovules.
