Answer 1

Right choice is (a) Tank – fuel pump – fuel filter – carburetor

The explanation is: The fuel flows from the fuel tank to the fuel pump where the fuel is pumped to high pressure and then the high-pressure fuel enters the filter and the dust and retained in the filtered and then the fuel is sent into the carburetor.
