Answer 1

Answer: (b) varying

Explanation: The varying volume in the cylinder is filled with the working fluid during the operation of the engine. In internal combustion engines, particularly in two-stroke engines, the volume of the cylinder changes as the piston moves, creating varying volumes that are filled with the air-fuel mixture or exhaust gases at different points in the cycle.
