Detailed Solution

Concept- Reflection symmetry is a sort of symmetry that pertains to reflections. Line symmetry and mirror symmetry are other terms for reflection symmetry.
To write the English alphabets that have both horizontal and vertical reflectional symmetry in this question. To do so, we must first understand that mirror symmetry, also known as reflectional symmetry, is a symmetry generated by sketching the mirror image.
We know that an image's reflection has the property that each point of reflection is at the same distance as a true picture. When considering alphabets from A to Z, we require alphabets that read the same as the real alphabet after reflection.
As a result, the letters H, I, O, and X are the only four that have both horizontal and vertical symmetry.
Hence, the correct answer is option (2) .
