CorrectNot quiteAnswer C

Correct answer: C

"Had the pilot not ..." means "if the pilot had not ...". P opens the condition, and "not" needs its verb: R "spotted the smoke in time,".
The comma ends the condition, and the result follows: S "the plane might have", which needs a past form: Q.
So the order is PRSQ: "Had the pilot not spotted the smoke in time, the plane might have caught fire over the sea."

Worth noting

RPSQ opens with "spotted the smoke", a verb with no subject. The "had the pilot not" that gives it one must come first.
