Best answer
The correct option is (a) 750

Best explanation: In a 4-stroke engine the power stroke is produced in every two rotation of the crankshaft.

Number of power strokes=\(\frac{RPM}{number \, of \, crank \, rotation \, for \, one \, complete \, rotation \, of \, the \, flywheel}\)

Hence, \(\frac{1500}{2}=750\)
