Which of the following pairs has the same relationship as it is between JL and WZ?

The relationship is about the number of letters between the two letters of each pair. In JL, exactly one letter (K) lies between J and L. In WZ, two letters (X and Y) lie between W and Z. So the first pair has a one-letter gap and the second has a two-letter gap.

Option A matches this exactly. In AC, only B lies between A and C, a one-letter gap. In RU, S and T lie between R and U, a two-letter gap. The order of the gaps is also the same as in the given pair.

• B (AB, PW): AB has no letter between its two letters, and PW has six letters between them. Neither matches.
• C (PR, LM): PR has one letter between (Q), but LM has none.
• D (TU, WX): both pairs are adjacent, so both gaps are zero, not one and two.

The core concept is letter-position spacing, a standard reasoning device in Prelims aptitude papers. Fast, accurate counting of gaps (or position differences in the alphabet) saves time on such items.

Trap: aspirants count the alphabetical difference inconsistently, or confuse 'letters between' with 'difference in position'. Always count the letters in between explicitly.
