Collinear points are the set of points that lies on the same straight line. In the term collinear, co refers to togetherness and linear refers to line. So collinear refers to the points that hang on the same line together. The point that does not lie on the same line is called as non-collinear points.
Check all options:
A. Points R, D, and E do not lie on the same straight line, they are non-collinear points.
B. Points F, W, and R lie on the same straight line, they are collinear points.
C. Points Q, E, and T lie on the same straight line, they are collinear points.
D. Points W, E, and T do not lie on the same straight line, they are non-collinear points.
Answer: correct choice is B and C.
