Dear Sir, answer C, a mixture of petrol an air is sucked in, but some people call this stroke1

Thanks for the invitation. Sorry I do not know the right answer.

The Answer is C

Because First Petrol is mixed with Air in the Carburettor and then this mixture is sucked in the combustion chamber in the suction stroke.

Choice.C

Four stages of cylinder stroke;

Suction (mixture of air and gas, usually the ration is15:1)

Compression

The correct answer must be C due to the Presence of Petrol and Air without which there will be no explosion in the bore
