Option (B).
CD lies on the plane M, but its not clear that angle between the plane M and P is 90°.
False.
Option (C).
A, B and C are coplanar.
Since, these three points lie on the plane M, they are coplanar.
True.
Option (D).
Plane M intersects plane P in FH.
Since, line of intersection of the two planes M and P will be FH.
