In a single acting steam engine

A The steam is admitted on one side of the piston and one working stroke is produced during each revolution of the crankshaft
B The steam is admitted, in turn, on both sides of the piston and one working stroke is produced during each revolution of the crankshaft
C The steam is admitted on one side of the piston and two working strokes are produced during each revolution of the crankshaft
D The steam is admitted, in turn, on both sides of the piston and two working strokes are produced during each revolution of the crankshaft

Correct Answer: The steam is admitted on one side of the piston and one working stroke is produced during each revolution of the crankshaft
