Select the pair that follows the same pattern as that followed by the two…

A letter-pair coding pattern applies a fixed alphabet-position shift to each of the three letters of a word: the first letter is shifted by one fixed amount, the second letter by another fixed amount, and the third letter by a third fixed amount, and this same three-letter shift sequence must hold for every valid pair in the pattern.

1. In RUI: OSM, R (18th letter) moves 3 places back to O (15th), U (21st) moves 2 places back to S (19th), and I (9th) moves 4 places forward to M (13th), giving the shift sequence (−3, −2, +4).

2. In FCV: CAZ, F (6th) moves 3 places back to C (3rd), C (3rd) moves 2 places back to A (1st), and V (22nd) moves 4 places forward to Z (26th) — the same shift sequence (−3, −2, +4), confirming it as the governing pattern.

3. Applying (−3, −2, +4) to MOQ : M (13th) moves 3 places back to J (10th), O (15th) moves 2 places back to M (13th), and Q (17th) moves 4 places forward to U (21st), reproducing MOQ : JMU exactly.

Cross-check against every option pair by computing its own three-letter shift sequence:

Only MOQ : JMU reproduces the full (−3, −2, +4) sequence established by both given pairs, so it is the pair that follows the same pattern.
