Which of the following is herbicide?

Correct option is A

Correct Answer: (C) 2,4-D

Explanation:
2,4-D (2,4-Dichlorophenoxyacetic acid) is a widely used herbicide that helps control broadleaf weeds in agriculture, lawns, and forestry. It works by mimicking the plant hormone auxin, causing uncontrolled growth and eventually killing the weeds.
Information Booster:
2,4-D is a selective herbicide, meaning it targets specific weeds without harming crops like wheat, maize, and rice.
It was one of the first major herbicides developed and is still widely used worldwide.
It is commonly applied in liquid form and is effective against dandelions, clover, and other broadleaf weeds.

(B) BHC – Benzene Hexachloride, an insecticide, used in agriculture and as a treatment for lice and scabies.
(D) Bordeaux Mixture – A fungicide, made of copper sulfate and slaked lime, used to control fungal diseases in grapes, potatoes, and tomatoes.
