B.

Answer
D.

Answer: Option C

Solution

Answer: Option C
Solution:
The ovule is inverted with the body fused to the funicle, the micropyle lying close to the hilum and facing the placenta. It is Anatropous.
An anatropous ovule is having or being a plant ovule inverted so that the micropyle is bent down to the funiculus to which the body of the ovule is united.
It is one in which curvature during development results in the displacement of the micropyle to a position adjacent to the funiculus base, this is the most common ovule type of the angiosperms and is presumed to be ancestral.
