The correct answer to this question is B, ovules. They are found in seed plants, located in the gynoecium. Ovules consist of three parts. These parts include the integument, which forms the tough, outer layer. Then there is the nucellus, which is the largest part of the ovule and is home to the nutritive tissue and embryo sac.

The last part is the megagametophyte, which produces an egg cell for fertilization. There are several different patterns of the ovule including apical, basal, marginal, and free-central presentations. Along with these patterns, there are six types of ovules which include hemi-anatropous, orthotropous, anatropous, amphitropous, and circinotropous.
