Answer 1

Answer:(c) pump fuel so that it reaches carburettor

Explanation: The function of the fuel pump in a petrol engine is to pump fuel from the fuel tank to the carburettor, ensuring a continuous supply of fuel to the engine for proper combustion. It does not directly inject fuel into the cylinder or serve as a backup if the carburettor fails. The fuel pump is essential for maintaining the fuel supply under the right pressure.
