Select the letter that will come next in the following series.
D, F, H, J, L, ?

Given: D, F, H, J, L, ?

Logic: The letters are increasing by 2 positions in the alphabet.

D + 2 = F, F + 2 = H, H + 2 = J, J + 2 = L,

The next letter will be:

L → ? (L + 2 = N)

Thus, the next letter in the series is N.

Thus, the correct option is (c) N.
