Number of letters in alphabet.

**The reasoning** The English alphabet — which is what we use in Nigeria and test in exams like JAMB, WAEC, and NECO — contains exactly **26 letters**. These run from A to Z: A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z. Count them carefully, and you'll always land on 26. This is a fixed fact — it never changes. **Why the wrong options tempt you** - **24** might come from miscounting or confusing it with hours in a day. - **25** is close enough to make you second-guess if you're rushing. - **27** could trick you if you mistakenly add a punctuation mark or extra character (like counting "and" or a space). The trap here is *assuming* instead of *knowing*. Under exam pressure, doubt creeps in. **Quick takeaway** The English alphabet has 26 letters, A to Z — lock this in your memory like your phone number, because it's tested as a basic literacy checkpoint.
