Which of the following uppercase English letters looks IDENTICAL to its reflection across a vertical plane mirror placed directly to its right?
Options:
(A) F
(B) M
(C) P
(D) R
Answer Key:
B
Step-by-Step Solution & Explanation
**Method 1: Bilateral Symmetry Rule**
A 2D glyph appears identical to its image in a vertical mirror if and only if it exhibits a vertical line of reflection symmetry. The letter 'M' is bilaterally symmetric about its vertical central axis, whereas 'F', 'P', and 'R' lack vertical symmetry and undergo lateral inversion. Option **B** is correct.
