Answer:
Option (2)
Explanation:
Option (1).
Points A, B and D are collinear.
True. (On plane S)
Option (2).
Points A, B, C and E are coplanar.
False.
(Points A, B and D are on plane S and points C and E are on plane R)
Option (3).
BE intersects line 'n' at point B.
True.
Option (4).
CB ⊥ AD
(CB lies on plane R and AD lies on perpendicular plane S).
Option (5).
Line 'm' ⊥ plane R.
True.
(Line m is on plane S which is perpendicular to plane R).
Option (6).
Plane R intersects plane S at line n.
True.
Plane R and Plane S are perpendicular and the point of intersection is line 'n'.
Therefore, Option (2) is incorrect.
