The following is the list of pesticides:

[a] B.H.C.

[b] D.D.T.

[c] NaCN

[d] Heptachlor

[e] Carbendazim

Choose the correct answer from the options given below:

Correct option is D

Correct option: (d) — (a) to (d) are banned in India except [e]
Explanation:
· [a] BHC (Benzene Hexachloride) – ❌ Banned
· [b] DDT – ❌ Banned/restricted (only limited public health use allowed, not agricultural)
· [c] NaCN (Sodium cyanide) – ❌ Banned due to high toxicity
· [d] Heptachlor – ❌ Banned (persistent organochlorine)
· [e] Carbendazim – ✔️ Not banned (still permitted fungicide under regulation)
Thus, only Carbendazim is not banned among the listed chemicals.
�� Key Points
· Many organochlorine pesticides are banned due to persistence and bioaccumulation.
· Carbendazim is a systemic fungicide still in use (regulated).
