Answer:
The third statement is true reason.
Step-by-step explanation:
See the diagram given with this question.
The conclusion is that lines l₁ and line l₂ intersect only at point P.
A line contains at least two points - is not the reason for this conclusion.
Through any two different points, exactly one line exists - is also not the reason for the above conclusion because we are concerned about only P point here.
If two lines intersect, then exactly one plane contains both lines - is not the actual reason as there is no mention of a plane in the conclusion.
If two lines intersect, then their intersection is exactly one point - this gives the actual reason for the conclusion above and the only point of intersection of two lines l₁ and l₂ is point P only. (Answer)
