Show answer & explanation
Correct answer: B
Concept
A triad of the form P - Q - R is an analogy built on positional operations: one operation carries P to Q and a second operation carries Q to R, and the same ordered pair of operations must recur, step for step, in the triad being matched. Each operation is described purely in terms of letter positions, never in terms of which letters happen to be used. So the method is to read the two given triads, write each step as a movement of positions, and then test which offered group of letters reproduces both steps in the same order.
Applying the idea to the two given triads
Step 1, from the opening group to the middle group: the letters occupying places 1 and 2 exchange places, while places 3 and 4 are untouched. WALK becomes AWLK, and SLIT becomes LSIT.
Step 2, from the middle group to the closing group: the letter now standing at the front moves to the end and the other three letters each shift one place to the left. This is a single cyclic left rotation. AWLK becomes WLKA, and LSIT becomes SITL.
The rule is therefore: exchange the opening pair of letters, then rotate the whole group one place to the left.
Cross-check
Applying that two-step rule to the opening group of each offered triad gives:
Opening group | After exchanging the opening pair | After the left rotation | Closing group as offered |
|---|---|---|---|
OPTS | POTS | OTSP | SPTO |
BUSH | UBSH | BSHU | BSHU |
VANS | AVNS | VNSA | SNAV |
NEAR | ENAR | NARE | EARN |
Contrast
OPTS - POTS - SPTO reproduces the opening exchange, but rotating POTS one place to the left yields OTSP, whereas the group offered is SPTO.
VANS - VNAS - SNAV exchanges the middle letters A and N rather than the opening pair, so it departs from the rule already at Step 1; VNAS to SNAV exchanges the two end letters instead of rotating.
NEAR - ENAR - EARN reproduces the opening exchange, but rotating ENAR one place to the left yields NARE, whereas the group offered is EARN, which keeps E at the front.
Only BUSH - UBSH - BSHU satisfies both steps: BUSH gives UBSH by exchanging B and U, and UBSH gives BSHU by the cyclic left rotation. Hence BUSH - UBSH - BSHU follows the same logic as WALK - AWLK - WLKA and SLIT - LSIT - SITL.
