(1) A + B = 8/9 of total. This means C occupies = 1 - 8/9 = 1/9 of total area.
But nothing else given, so we cannot say what fraction is section A. Not sufficient.

(2) Let area of section C = x, thus area of section B = 3x. But this is not enough to know what fraction is section A. Not sufficient.

Combining the statements, C = 1/9 , thus from statement 2, B = 3/9. Together, C + B = 1/9 + 3/9 = 4/9
Thus A occupies = 1 - 4/9 = 5/9 of total area. Sufficient. Hence C answer
