Answer 2

The odd one out is K.

• From the following, C stands for Carbon, N stands for Nitrogen, K stands for Potassium, and O stands for Oxygen.
• If we look into the Periodic Table, the Carbon(C), Nitrogen(N), Oxygen(O) are in the same period and that is period 2 whereas Potassium(K) is in period 4.

• We know that Carbon(C), Nitrogen(N), Oxygen(O) are non-metals and Potassium(K) is considered to be an alkali metal.
