Show answer and explanation

Correct answer: (B) Option B in the figure

Explanation

Reflection about the horizontal X-axis reverses each letter top-to-bottom while preserving the left-to-right order. In particular, the asymmetric letters R, N, G and L must all be vertically reflected; a rotation or a left-right mirror is different. The matching rendering is **B**.
