Consider the line L given by the equation
Let Q be the mirror image of the point (2, 3, -1) with respect to L. Let a plane P be such that it passes through Q, and the line L is perpendicular to P. Then which of the following points is one the plane P?

Correct Option - 1
Detailed Solution:Equation of plane to line and passes through the point
(2, 3, -1) is 2(x – 2) + 1(y – 3) + 1 (z + 1) = 0
=> 2x + y + z – 6 = 0 .(i)
Hence point (1, 2, 2) satisfies equation (i)
