The question is missing a diagram and not written well. I found a similar question and attached it here as reference. The question is as follows:
Which statement is true about the points and planes?
A)The line that can be drawn through points C and D is contained in plane Y.
B) The line that can be drawn through points D and E is contained in plane Y
C) The only point that can lie in plane X is point F.
D) The only points that can lie in plane Y are points D and E
Answer:
B) The line that can be drawn through points D and E is contained in plane Y
Explanation:
Both point D and E are on the plane Y. Therefore only one straight line possible between D and E which is through and contained in the Y plane.
C is not on plane Y or X. if a line is drawn between C and D, it will passes through plane X and Y.
Point F are not the only point that can lie on X plane, the same goes for point D and E are not the only points that can lie on Y plane.
