Which option can replace ‘?’ from given relation? FAN : IDQ :: SAT : ?

To find the missing letters in the analogy FAN : IDQ :: SAT : ?, let's analyze the shift in the alphabet for each position.

Step-by-Step Analysis
Compare FAN to IDQ:

F to I: F is the 6th letter, I is the 9th letter. (6 + 3 = 9). Shift = +3.

A to D: A is the 1st letter, D is the 4th letter. (1 + 3 = 4). Shift = +3.

N to Q: N is the 14th letter, Q is the 17th letter. (14 + 3 = 17). Shift = +3.

Pattern: Each letter in the first word is shifted forward by 3 positions in the alphabet.

Apply the Pattern to SAT:

S + 3 = V (S is 19, 19 + 3 = 22, which is V).

A + 3 = D (A is 1, 1 + 3 = 4, which is D).

T + 3 = W (T is 20, 20 + 3 = 23, which is W).

The resulting code is VDW.
