Answer:

Correct Answer: D

Solution:

In Pinus, the embryo is straight and consists of a short axis bearing a ring of about ten slender, yellow cotyledons at the end, away from the micropylar end.

In Pinus, more than one embryo come from a single egg by the splitting of the product of a single fertilization, termed as cleavage polyembrony.
