The bending of ovule is like a horse shoe in

Answer: Option A

The bending of the ovule is like a horseshoe in Anatrophous.
Anatropous is a condition of 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.
An anatropous ovule 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 angiosperm and is presumed to be ancestral.
