Double fertilization refers to the process in flowering plants in which two sperm cells fertilize two different structures within the female reproductive system. One sperm cell fertilizes the egg cell, forming a diploid zygote, which will develop into the embryo of the seed. The other sperm cell fertilizes two polar nuclei in the central cell, resulting in a triploid nucleus, which will give rise to the endosperm, a nutrient-rich tissue that provides the developing embryo with nourishment. Therefore, double fertilization produces both the zygote and the endosperm, making Option A the correct answer.
