According to me, option B is correct.

B is the right answer.

According to Ts diagram beginning temp less in suction stroke.

At the Beginning of the suction stroke, everything is hot, the air fuel mix comes in but has a lot of work to do cooling everything down. By the time it has sucked in a whole cylinder of air, the chamber cylinder temperature will be at its lowest point at the bottom of the cycle.

Option B is correct.

As per the T-S diagram of 4 stroke engine. Option A is right.

As pv=nrt since at the beginning of suction stroke pressure will be less and volume will be less hence definitely temp will less compare to end of suction stroke because p and v value will be high.

For working fluid temperature is minimum at beginning of suction stroke.

For other things like piston, cylinder head, resedual exhaust gases temperature is minimum at the end of suction stroke.

Volume increase at the end of sunction stroke. But at the same time mass increase. So the net effect will be decrease in temp. At the end of the sunction stroke. Also, it is no where mention in the T-S diagram.

Please explain it clearly.

Answer A is correct,

In question they have asked temperature inside cylinder not temperature of cylinder.
