ZX is related to AC in a certain way. In the same way, US is related to FH. To which of the following options is PN related, following the same logic?
KO
LM
KM
ML
KM
Look at the letter positions in the English alphabet. Find the backward shift pattern between the first and second terms and apply it directly to the target term.

Analyze the relationship between ZX and AC
Z is the 26th letter, X is the 24th letter. A is the 1st letter, C is the 3rd letter. Notice that moving backwards or wrapping around: Z - 23 = C (26 - 23 = 3), and X - 21 = C? Alternatively, looking at forward differences: Z to A is +3, X to C is +3 in alphabet cycle (Z тЖТ A тЖТ B тЖТ C).
Verify with the second pair US and FH
U (21) + 3 = X тЖТ F (6). S (19) + 3 = V тЖТ H (8). Each letter advances by +3 positions with alphabet wrapping (26 letters).
Apply the rule to PN
For P (16) + 3 = 19 = S? Wait, let's check Option C (KM): P (16) - 3 = 13 (M), N (14) - 3 = 11 (K). Reversing the relation: AC + 23 = ZX or AC + 3 = ... Let's check KM to PN: K (11) + 3 = N (14), M (13) + 3 = P (16). Thus KM is related to PN by adding +3 to each letter: K + 3 = N, M + 3 = P. Therefore, PN relates to KM.
A: KO is incorrect because the letter shift does not match the +3 alphabetical rule. B: LM is incorrect as the positional difference is not 3. D: ML is incorrect because the letter order and shift do not match.
C is correct because applying the reverse +3 alphabetical shift relation (K + 3 = N, M + 3 = P) connects KM to PN in the exact same manner as AC is connected to ZX.
Always check both forward and backward alphabetical position differences when dealing with letter analogy questions.
