Plane Mirror Reflection Principle Steps:

• Object O forms virtual image I behind the mirror, same distance as O is in front.
• Ray from top of O hits mirror at X and reflects per law of reflection (angle i = angle r).
• Reflected ray, when traced backward, intersects at top of I.
• Observer sees ray appearing to originate from top of I.

Why D is correct:

• D states the ray reflects as if coming from the image point, matching virtual image formation where rays diverge from I (optics definition).

Why the others are wrong:

• A: Reflected ray cannot pass through O, as it diverges away from the mirror.
• B: Ray from top of O corresponds to top of I, not bottom (image is erect).
• C: Misstates path; actual appearance is from I's top, but D precisely captures the "as though" divergence.

Final answer: D
