The answer is (a) Intake, Compression, Power, Exhaust.
The fourth-stroke engine cycle or the commonly known as the four cycle is a type of engine that completes four separate strokes while turning a crankshaft. First is the Intake where the piston begins at TDC. Second is the compression where it begins at BDC and the piston compresses the air-fuel mixture for ignition. Third is combustion where the second revolution of the cycle starts. Last is the exhaust where the piston once again returns to TDC from BDC.
