I had been asked this question in an internship interview.

I want to ask this question from Exhaust Gas Recirculation topic in chapter Engine Emissions and their Control of IC Engine

Answer 1

The correct answer is:

(a) Fuel vapours

A vent valve is provided for the carburettor to allow the flow of fuel vapours. This valve helps in managing the fuel vapour emissions and directs them to the charcoal canister or other systems designed to capture and store the vapours, preventing them from being released into the atmosphere.
