Which alphabet is a question?

Hint: The phonemes of particular spoken languages are represented by an alphabet, which is a standardized set of basic written symbols or graphemes (called letters). Not all writing systems use characters to represent language in this way.

Complete answer:
The present English alphabet consists of 26 letters, each of which has an upper- and lower-case version. the modern English alphabet, which consists of 26 letters without diacritics, digraphs, or special symbols

The actual shape of printed letters varies depending on the typeface (and font), and the typical printed form can differ greatly from the shape of handwritten letters (which varies from person to person), especially cursive.
A a, B b, C c, D d, E e, F f, G g, H h, I I J j, K k, L l, M m, N n, O o, P p, Q q, R r, S s, T t, U u, V v, W w, X x, Y y, and Z z are the letters of the alphabet in lowercase and uppercase.

Out of all the above-given letters, the English alphabet that is always used to ask a question is Y as it sounds much like ‘why’, which is used whenever someone wants to ask a question.

Note: It's important to remember that a letter is just a shape that symbolises a sound when it's used in a word or sentence. Furthermore, because a letter or combination of letters might represent more than one sound, the only method to distinguish alphabet letters when discussing them is to use their names.
