Planes a and b intersect. which describes the intersection of plane a and line m? line k line n point x point w

In analytic geometry, the intersection of a line and a plane in three-dimensional space can be the empty set, a point, or a line:

In your case line m is not parallel to the plane A and is not embedded in the plane, then the intersection is the point. Since point X is common point of the line m and the plane A, then the intersection of plane A and line m is point X.

correct choice is C.
