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.

RS kurmi p-222.
Look at the pictures of OTTO CYCLE, everyone.
Otto cycle in short: P-T is lowest at the beginning of compression stroke
P-T is highest at the beginning of expansion stroke.
End of discussion. You can thank me later.

As per my knowledge; the min temp inside the cylinder will be at the end of the suction stroke So, option B is the correct answer.

It should be at the end of the suction stroke.

Fresh charge with room temp is admitted to the cylinder in the suction stroke. As much as fresh charge better it cools down the cylinder by absorbing heat. So, that temperature decreases.

In the TS diagram, beginning of compression Temperature in the minimum that is the end of suction.

At the end of suction stroke the intake air and fuel temperature will be less so according to my opinion the option B is correct.

I think answer B is correct. The inside surface area of cylinder is still hot at the beginning of suction some heat will be transfer to the air by convection at the end of suction.
