If $a$, $b$ and $c$ are positive, consecutive terms of a geometric sequence (that is, $\frac{c}{b} = \frac{b}{a}$), then the graph of $y = ax^2 + bx + c$ is

(A) a curve that intersects the $x$-axis at two distinct points (B) entirely below the $x$-axis (C) entirely above the $x$-axis (D) a straight line (E) tangent to the $x$-axis
