Q1. Select the related letters from the given options to replace the question mark: HJLN : SQOM :: DFHJ : ?
Explanation
The relation uses opposite letters of the English alphabet. H is paired with S, J with Q, L with O and N with M; in each pair, the alphabet positions add to 27. Applying the same rule to DFHJ gives D to W, F to U, H to S and J to Q. This forms WUSQ. The other letter groups contain at least one position that is not the opposite alphabet pair, so they do not preserve the given relation.
