The foot of perpendicular from the origin $$O$$ to a plane $$P$$ which meets the co-ordinate axes at the point $$A, B, C$$ is $$(2, a, 4)$$, $$a \in N$$. If the volume of the tetrahedron $$OABC$$ is 144 unit$$^3$$, then which of the following points is NOT on $$P$$?

A

$$(0, 4, 4)$$

B

$$(3, 0, 4)$$

C

$$(0, 6, 3)$$

D

$$(2, 2, 4)$$
