Answer is 1 because only in one cylinder fire in 4 cylinders in line on one revolution of the crankshaft.

Even-though it is inline, it doesn't mean that ignition in only one cylinder can meet the requirement in all four engines.
But every cylinder requires separate ignition.
And since the working cycle will be completed in 2 revolutions of the crankshaft, therefore for the first revolution of crankshaft two firing strokes will be completed and next two will be complete in a second revolution of the crank shaft.
