The song Jana-gana-mana, composed originally in Bangla by Rabindranath Tagore, was adopted in its Hindi version by the Constituent Assembly as the National Anthem of India on January 24, 1950.

(B) Allethrins

Allethrins are active chemicals commonly used in mosquito repellents and insecticides to deter or eliminate mosquitoes. They belong to a class of synthetic pyrethroid insecticides, which are designed to mimic the insecticidal properties of pyrethrins, natural insecticides derived from chrysanthemum flowers. These chemicals are effective in repelling and killing mosquitoes and other insects. The other options (Benzene Hexachlorophene, Atropine, and 2-Isopropoxiphimyal) are not typically used for mosquito control.

As of September 2023, there have been 106 amendments of the Constitution of India since it was first enacted in 1950.
