उत्तर

Both (A) and (R) are true, but (R) is not the correct explanation of (A).

Explanation:

As perisperm comes from the nucellus, a diploid maternal tissue, it is, in fact, diploid. During embryonic development, the nucellus is depleted; nevertheless, in certain instances, it endures, which is unrelated to its ploidy.
