Let's Assume That The Given Line is , and the point is , which is not on .
Now, Let's assume, We have drawn a perpendicular on , and intersecting line at a point.
We have to prove that, this is the line passing through that is to .
Now, we will use a construction.
Let's construct another perpendicularon from point .
Proof:
We have,
perpendicular .
Also, perpendicular .
So, || . [Both are perpendiculars on the same line.]
Now since both and have point .
So, and are the coincident lines or parallel lines and only one of them passes through point a}
answer:
A. and cannot both be perpendicular to

The statement of the problem is not sufficient to get a single answer from among the answer choices.
Choice B makes no sense and so can't be a right answer; lines are infinite in length and can't be congruent.
Choice C is not right. You can certainly make BV and FG perpendicular, but that will be a very special case.
Now what about choices D and E....
If two lines are perpendicular to a given line and both pass through a point P not on that line, then the two lines are the same line, and they will intersect the line at the same point.
And there is nothing in the statement of the problem that says BV and FG can't be the same line.
So answer choices D and E are both possible in one special case, but they are not true in the general case.
And answer choice A is not true in the special case where BV and FG are the same line.
So, because the statement of the problem does not specify that BV and FG are not the same line, none of the conclusions A to E is possible.
