The answer is (C)

statement 1

when x = 0 y = 6

since Y = 0^2 - 3*0 + 6 = 6

Since this is a parabola, a line parallel to X - Axis will intersect in two points or in zero places. See diagram for illustration.

Statement 2

Statement 2 is meaningless !

both statments

togther will know that the line will intersect in zero places

I think this problem is out of GMAT scope.
