Auxin is a growth promoter, generally produced by the growing apex of stem and root of the plants.
The naturally produced auxin is Indole-3-Acetic Acid (IAA). Some of the synthetic auxins are Indole-3-butyric acid (IBA), 2,4-Dichlorophenoxy Acetic Acid (2,4-D), and Naphthalene acetic acid (NAA).
NAA (Naphthalene acetic acid) is used for preventing fruit drop in apples before they are ripe.
So, the answer is D.
