Answer:
Option (4)
Explanation:
Since point R is on the same plane as the line SP has, perpendicular line will have the same plane.
Lines passing through the point R are, KR, RQ and RS.
But the line which is in the same plane as of SP are, RS and RQ.
Perpendicular line to the line SP is line RS only.
Therefore, line perpendicular to line SP and passing through a point R is SR.
Option (4) is the correct option.
