My paraphrase: Measures employed cannot compensate for lack of actual flying time.

Here I am struck between [spoiler]C & D[/spoiler]. I want to make sure my analysis of C & D is accurate.

C: Since no of airline crashes are going to decrease if pilot training programs focus on actual flying times, this is going to strengthen the argument. But, this is not a necessary assumption.

D: Actual flying time is not an important contributor to pilot error --> then the conclusion that airlines should rethink their approach is significantly weakened.

OA is D, but not able to pick D in less than 2 min.

Is it safe to say that such a comparison is misleading, and hence a reason to rule out C? For example, the number of plane crashes might depend on the number of flights; perhaps the season is busy, or not. At any rate, something other than flight time could cause a change in the "number" of accidents, no?
