Let the function $$f(x) = 2x^3 + (2p-7)x^2 + 3(2p-9)x - 6$$ have a maxima for some value of $$x < 0$$ and a minima for some value of $$x > 0$$. Then, the set of all values of $$p$$ is

A

$$\left(\frac{9}{2}, \infty\right)$$

B

$$\left(0, \frac{9}{2}\right)$$

C

$$\left(-\infty, \frac{9}{2}\right)$$

D

$$\left(-\frac{9}{2}, \frac{9}{2}\right)$$
