The correct is option (D) The endosperm has 36 chromosomes.

After double fertilization, the endosperm is a tissue that develops inside the seeds of the majority of flowering plants. In most species, it is triploid (three chromosome sets per nucleus), which may be auxin-driven. In addition to providing nutrition in the form of starch, it also surrounds the embryo and may also contain oils and proteins. As a result, endosperm may become a source of nutrition for animals. For instance, barley endosperm is the primary source of sugars for brewing beer, while wheat endosperm is ground into flour for bread (whole wheat flour also contains the rest of the grain).
