Which of the following statements is/are correct with reference to the hydrogen sulphide (H2S)?

Which of the following statements is/are correct with reference to the hydrogen sulphide (H2S)?

A. It is a poisonous, corrosive, and flammable gas.

B. It is the primary gas produced from the microbial breakdown of organic matter in the absence of oxygen.

C. Both A & B

D. None of these

Explanation:

Scientists from the city-based Centre for Nano and Soft Matter Sciences (CeNS) have developed an electronic nose with biodegradable polymer and monomer that can detect hydrogen sulphide (H2S). H2S is the primary gas produced from the microbial breakdown of organic matter in the absence of oxygen, and this necessitates easy detection of its emission from sewers and swamps.
