Answer

Answer: Option D

Solution

Answer: Option D
Solution:
2,4,5-tricholorophenoxyacetic acid (2, 4, 5-T), is a chlorophenoxy acetic acid herbicide used to defoliate broad-leafed plants.

Isoproturan is a member of the class of phenyl ureas that is 1,1-dimethylurea substituted by a p-cumenyl group at position 3. A selective, systemic, herbicide used to control annual grasses and broadleaf weeds in cereals.

Butachlor is an aromatic amide that is acetamide in which the amide nitrogen has been replaced by a butoxymethyl group.

Dinoseb is a common industry name for 6-sec-butyl-2, 4-dinitrophenol, a herbicide in the dinitrophenol family. It is now here related to carbamates.
