Answer 1

Answer: (C)

2,4-D

2,4-D is the abbreviated form of 2,4-Dichlorophenoxyacetic acid. It is a chemical compound which is commonly used as a weedkiller. It is the synthetic form of auxin. The compound was used by the U.S. military to clear the trees by defoliation. These are used for clearing the areas of woody trees and some other herbaceous weeds. These hormones cause defoliation of the trees and thereby, killing the trees.

Thus, the correct answer is option C.
