At the end of the exhaust, the temperature of the cylinder is high. At the beginning of suction stroke the fresh air enters the cylinder (low temperature) and by the end of the suction stroke, the intake fresh air becomes hot (high temperature) why? Because it comes in contact with cylinder wall and gets warm and warm until the suction ends. Also by T-S diagram, it is clearly shown that minimum temperature is at the beginning of the suction stroke.
So, the answer is option A.
So, the answer is option A.

Answer B is 100% correct. It's because when suction stroke begin, the temp of incoming air is high due to the high temp of intake manifold. But as the suction is completed, the P decrease inside the cylinder which lead to reduction in temperature.

Please tell me, which is the final answer?

I think option A is correct. Because at the beginning of suction stroke air temperature is low. At the end of suction, air temp increase as the air will be in contact with hot cylinder.

A is the correct answer. Because, the question is given for minimum temp. If it is maximum temp then it option B is correct. Due to piston moves to TDC the pressure increase and temp also increase.

In question, the temperature is within the cylinder. It should be at the end of suction.

Here asking about working fluid temperature, not cylinder temp. So, I think option 1 is correct.

A is correct one. As I have checked TS diagram.

Statement is: In a four stroke cycle, the minimum temperature INSIDE THE ENGINE CYLINDER.
