Answer and explanation
Correct answer: 5
The word GANIT contains the letters G, A, N, I, and T. None of these five letters is repeated, so the set of distinct letters is {G, A, N, I, T}. The cardinality of a set counts each different element only once, giving |A| = 5. Therefore, option B is the correct answer.
