Answer:
The correct option is 1.
Step-by-step explanation:
Given information: X⊥A and X⊥B.
It means X is perpendicular to A and X is perpendicular to B.
If two lines are perpendicular to a same line, then both lines are parallel to each other.
Let we have three line l,m and n. If l ⊥ m and l⊥n, then m║n.
Here X⊥A and X⊥B. So, A║B.
Therefore, the correct option is 1.
