Match List I with List II. Choose the correct answer from the options given…

Concept

In a coding–decoding match, each word is converted to its code by ONE fixed rule applied letter-by-letter across the whole word. To match a word to a code you must find the single positional-shift rule that turns every letter of the word into the matching letter of the code, and then it must work for all four words simultaneously.

Finding the rule

Shift each letter by its alphabet position (A=1 … Z=26) and look at the pattern of shifts. Testing the words against the codes, exactly one rule is consistent: alternate +1, −1, +1, −1, +1 across the five letters (odd positions move one letter forward, even positions move one letter back).

Applying the rule (trace each word)

1. QUAKE: Q→R (+1), U→T (−1), A→B (+1), K→J (−1), E→F (+1) = RTBJF.

2. OFTEN: O→P (+1), F→E (−1), T→U (+1), E→D (−1), N→O (+1) = PEUDO.

3. PEACH: P→Q (+1), E→D (−1), A→B (+1), C→B (−1), H→I (+1) = QDBBI.

4. DRIVE: D→E (+1), R→Q (−1), I→J (+1), V→U (−1), E→F (+1) = EQJUF.

Result

So QUAKE–RTBJF, OFTEN–PEUDO, PEACH–QDBBI, DRIVE–EQJUF. Reading the list positions, this is A–III, B–IV, C–I, D–II.

Cross-check

Decode each code with the reverse rule (−1, +1, −1, +1, −1): RTBJF→QUAKE, PEUDO→OFTEN, QDBBI→PEACH, EQJUF→DRIVE — every pairing reverses cleanly, and no other shift pattern works for all four words, so the mapping is unique.
