The question is slightly tricky if you call it that.
It is mentioned 'inside the cylinder' which implies that they are asking about the temperature of the working fluid present inside the cylinder, which is obviously at the lowest temperature at the beginning of suction stoke. Where as if we talk about the cylinder temperature then B is correct after reasonable assumptions.

I think, the correct answer is option B.

I think Option B is correct because at the beginning of the suction stroke high-temperature exhaust gas had just omitted.
Hence, the chamber will be still hot. By the end of the suction, stroke chamber is filled with fresh air which is at minimum temperature.

By the end of suction stroke chamber is filled with fresh air which is atm temperature.

I think the answer [B] is right. Because at beginning of suction stroke exhaust gases are just delivered and hence temperature must be high and as suction happens atmospheric air comes in contact with engine cylinder and temperature reach it lowest value.

I'm not agree to this answer option b is correct because fresh air have low temperature than exhaust gases in the cylinder.

A/C to TS diagram minimum temperature at end of suction.

Option B is correct, because fresh air have low temp than exhaust gases in the cylinder.

A is correct because as suction stroke completes some fresh charge is already in while the cylinder is about to suck.
So its due to the fresh charges that the temperature is minimum.
