PQ is a thin rod on a horizontal table, RS is a plane mirror inclined at \( 45^{\circ}C\) to the horizontal as shown above. The image of PQ as seen in the mirror by the eye T is

A
horizontal
B
parallel to the mirror
C
at infinity
D
vertical
E
highly magnified
Verified Correct Answer: D.
Physical Principles & Numerical Solution
The mirror's 45^\circ tilt makes the horizontal rod PQ appear vertical. This occurs because the tilt rotates the image by 90^\circ for the observer, a common effect in optics with 45^\circ mirrors.
