A . as there are atleast 12 hours where the number of flights were >= 17 so min. flights = 17*12 = 204
2nd doesn't tell much.

I would go for A as well.

(1) tells us that for at least 12 out of 24 hours, there was at min 17 flights. 17*12 = 204.

(2) INSUFF

I also got A by the same reasoning, but now I wonder how important is the fact that the avg is a multiple of 12. You will still get A as an aswer, but why is that statment there... mmm :btw
