Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
DDT is classified as a Persistent Organic Pollutant (POP) under the Stockholm Convention.
Because it bioaccumulates in fatty tissues and persists in the soil for years, its use is strictly controlled worldwide.
Detailed Explanation:
In India, the use of DDT in agriculture was officially banned in 1989.
This was due to concerns regarding residues in food items and the development of resistance in agricultural pests.
However, DDT is still used in a very "restricted" manner for public health purposes.
The National Vector Borne Disease Control Programme (NVBDCP) uses DDT for Indoor Residual Spraying (IRS).
It is specifically used to control mosquitoes (Anopheles spp.) that transmit Malaria and sandflies (Phlebotomus spp.) that transmit Kala-azar (Leishmaniasis).
Hindustan Insecticides Limited (HIL) is the sole government entity authorized to produce DDT in India.
The chemical is sprayed on the internal walls of houses in endemic areas to kill vectors that rest there after feeding.
This is considered a "restricted" use because the chemical is not available for private sale or commercial use; it is strictly controlled by the Ministry of Health.

Step 2: Final Answer:
The restricted use of DDT in India is only permitted for human health (vector control) programs.
