Answer:
A
Solution:
A horizontal plane reflects the top half of the letter onto the bottom half.
Letters with a horizontal plane : B, C, D, E, H, I, K, O, X - from the given list : B, H, K, O, X (the two arms of K are mirror images about the horizontal line through the junction).
Letters without one : F (the top arm has no counterpart below), T (the stem lies below the bar only), Z (the top and bottom strokes do not reflect onto each other).
Ans. (A) Have a horizontal plane : B, H, K, O, X. Do not : F, T, Z.
