Answer:

Option (2)

Step-by-step 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.
