Geometry

The correct answer is "A plane contains B.at least three noncollinear points".

In Euclidean geometry, a plane is a two-dimensional flat surface that extends infinitely in all directions. To uniquely define a plane, we need at least three points that are not on the same line (noncollinear). If we have only two points, we can only define a line that passes through those two points, not a plane. And if the points are collinear, they still only define a line and not a plane. A plane can contain more than three nonc...
