Choose the missing terms out of the given alternatives. A, B, N, C, D, O, E, F, P, ?, ?, ?

The correct answer is A. G, H, I.

The pattern is that each letter is two places ahead of the previous letter in the alphabet, except for the letters N and O, which are swapped. This means that the next three letters in the pattern are G, H, and I.

Option B is incorrect because it includes the letter J, which is not in the pattern. Option C is incorrect because it includes the letter Q, which is not in the pattern. Option D is incorrect because it does not follow the pattern of two places ahead of the previous letter in the alphabet.
