Select the option that is related to the fifth term in the same way as the second term is related to the first term and the fourth term is related to the third term. SWEET : WSETE :: SALTY : ASLYT :: DRINK : ?

Correct — B. The letters are rearranged, not shifted.

Rule: swap letters 1 and 2, keep letter 3, swap letters 4 and 5.

SWEET gives WS | E | TE = WSETE, which matches.
SALTY gives AS | L | YT = ASLYT, which matches too.

DRINK: swap D and R to get RD, keep I, swap N and K to get KN.

RD + I + KN = RDIKN — option (b).

Why the others are wrong

• (a)
  ESJOL — This shifts every letter one place forward in the alphabet: D to E, R to S, I to J. The two worked pairs move letters about and never change them.
• (c)
  RDNIK — The first swap is done, but the last two letters are left in their original order, N then K. Positions 4 and 5 have to trade places as well.
• (d)
  DRIKN — Here the last pair is swapped but the first pair is not — D and R stay where they were. SWEET to WSETE shows both swaps are required.

An analogy of the form A : B :: C : D :: E : ? is a positional rearrangement far more often than an alphabet shift.

Test that first. If the second term uses exactly the same letters as the first, nothing has been shifted and only the order has changed.

Then number the positions and record where each letter lands. Here 1 and 2 trade places, 3 stays put, and 4 and 5 trade places — a rule you can apply to any five-letter word.

Key facts

• SWEET becomes WSETE by swapping positions 1 and 2 and positions 4 and 5.
• SALTY becomes ASLYT under exactly the same rearrangement.
• Applied to DRINK, that rearrangement gives RDIKN.

Common traps

• Reaching for an alphabet shift before checking whether the letters are merely reordered.
• Performing one of the two swaps and leaving the other pair untouched.
• Rearranging DRINK by eye instead of writing the positions out.
