Answer:
1. The correct option is B.
2. The correct option is D.
3. The correct option is C.
Step-by-step explanation:
1.
Let left plane is plane (1), right plane is plane (2) and horizontal plane is plane (3).
From the given figure it is clear that plane (1) and (3) intersect each other and plane (2) and (3) intersect each other.
Point B lies on the intersection of plane (1) and (3), and line x passes through the point B.
Point A lies on the intersection of plane (2) and (3), and line w passes through the point A.
So, line x and w represent the intersection of two planes. Only line x is available in the options.
Therefore the correct option is B.
2.
Line z is the which intersect plane (1) at point C. So, z is the line that intersects one of the planes.
Therefore the correct option is D.
3.
Line y passes through A and B. Points A and B are point which are lie on the intersection of planes.
The line y has points on three of the planes.
Therefore the correct option is C.
