Let us look at the definition of a plane in mathematics
In mathematics, a plane is a flat, two-dimensional surface that extends infinitely far.
A plane is not a line, it is a surface. And for us to have a surface, we must have at least 3 points that are non-collinear.
If the 3 points are colinear, we would still have a straight line and not a plane.
This makes the correct option to be "3 non-collinear points"
The answer is option D
