2. Endosulfan
3. Mancozeb
4. Phorate

Answer 1

Correct Answer - Option 1 : Gammexane 

The Correct Answer is Gammexane.

In view of environmental problems, the use of Gammexane has been reduced.

• Gammaxene (Lindane, gamma-hexachlorocyclohexane (-HCH), is an organochlorine chemical and isomer of hexachlorocyclohexane that has been used as lice and scabies medicinal remedy.
• Lindane is a neurotoxin that interferes with GABA neurotransmitter activity by binding to the picrotoxin binding site on the GABA receptor-chloride channel complex.
• Lindane is a carcinogen that affects the nervous system, liver, and kidneys in humans.
• The World Health Organization classifies lindane as "moderately dangerous," and the Rotterdam Convention on Prior Informed Consent restricts and regulates its international trade.

• The organophosphate phorate is used as an insecticide and acaricide.
• Endosulfan is an off-patent organochlorine insecticide and acaricide that is currently being phased out around the world. Endo and Exo are the two isomers that are often referred to as I and II.
• Mancozeb is a non-systemic dithiocarbamate agricultural fungicide that has a multi-site, contact-protective action. It's made up of maneb and zineb, two other dithiocarbamates.
