The logic here is
12$$^2$$ + 12 = 144 + 12 = 156
13$$^2$$ + 13 = 169 + 13 = 182
14$$^2$$ + 14 = 196 + 14 = 210
15$$^2$$ + 15 = 225 + 15 = 240
Second number is the sum of first number and square of first number.
$$\therefore\ $$15 - 230 is the odd one among the given number pairs.
Hence, the correct answer is Option D
