How is it possible at the beginning of suction the cylinder is full of air and the atm pressure is equal to the cylinder pressure and no more air is drawn into the cylinder?
Anyone, please explain this.

Pressure flow from higher to lower and to create suction pressure during intake the pressure must be less than atm if it is equal then there is no difference worst in case if high one.

Yes, option B is correct because I think compression stroke occurs after suction, and we should know that at the time of section stroke we need to pressure below or less than atmospheric pressure.

Yes, right @Kawale.
During suction pressure is lower than atmospheric pressure.
During suction pressure is lower than atmospheric pressure.

Answer is B.
Because before compression, there is suction of air and during suction, the pressure inside the compressor is less than atmospheric pressure.
Because before compression, there is suction of air and during suction, the pressure inside the compressor is less than atmospheric pressure.
