Answer: The correct option is (D) neither collinear nor co planar.
Step-by-step explanation: We are given to select the correct statement for the points R, S and T.
We know that
the points R, S and T will be co planar if they lie on the same plane
and
they will be collinear if they lie on the same straight line.
From the given figure we see that
the points R, S an T neither lie on the same straight line nor on the same plane.
Therefore, the points R, S and T are neither collinear nor coplanar.
Thus, option (D) is CORRECT.
