The correct option is D 1257777
A number is divisible by 9 only when the sum of its digits is divisible by 9.
568711 = 5 + 6 + 8 + 7 + 1 + 1 = 28, which is not divisible by 9.
962497 = 9 + 6 + 2 + 4 + 9 + 7 = 37, which is not divisible by 9.
1257777 = 1 + 2 + 5 + 7 + 7 + 7 + 7 = 36, which is divisible by 9.
966333 = 9 + 6 + 6 + 3 + 3 + 3 = 30, which is not divisible by 9.
1257777 is divisible by 9.
