C Correct answer
Explanation

Total phones from region O: 460 (A) + 650 (B) + 350 (C) + 500 (D) = 1960. Total phones from M, N, O, P: (560+450+460+200) + (460+350+650+390) + (402+455+350+580) + (660+680+500+390) = 1670 + 1850 + 1787 + 2230 = 7537. The calculation requires summing the specific subset.
