• B. Hydrogen
• C. Sulphur
• D. Chlorine

Answer 1

The correct option is D

Chlorine

The explanation for the correct option -

• Non-metals are those chemical elements that in reaction with metals (positively charged ions) gain electrons.
• These are brittle and bad conductors of heat and electricity.
• For example - Hydrogen$\left({\mathrm{H}}_2\right)$, Oxygen$\left({\mathrm{O}}_2\right)$, etc.
• Chlorine is a toxic gas with having greenish-yellow color.
• It has disinfecting properties due to which it is used in making chemicals like DDT, BHC, and Bleaching powder $\left({\mathrm{CaOCl}}_2\right)$.

The explanation for the incorrect options -

• Option A is incorrect because nitrogen is used in making fertilizers and insecticides.
• Option B is incorrect because Hydrogen is used in making Ammonia by Haber's process.
• Option C is incorrect because the major use of Sulphur is in making fireworks, gun powders, matches, etc.

Hence, Option D is the correct answer.
