Solution

The correct option is B Tetra ethyl lead
Tetra ethyl lead was commonly used until recently used as an anti –knocking agent which prevents the knocking sounds of the engine, increases the fuel efficiency and help in the wear and tear of valves within the motor. Knocking in the engine occurs when the combustion of fuel mixture present in the cylinder does not start off in response to the ignition by the spark plug.
