FIGH is related to KNLM in a certain way based on the English alphabetical order. In the same way, RUST is related to WZXY. To which of the following options is HKIJ related, following the same logic?​​

Given: FIGH is related to KNLM in a certain way based on the English alphabetical order. In the same way, RUST is related to WZXY.

Logic: Letters are increasing + 5 place in English alphabetical order.

FIGH $$\rightarrow$$ KNLM

F → K (+5), I → N (+5), G → L (+5), H → M (+5)

RUST $$\rightarrow$$ WZXY

R → W (+5), U → Z (+5), S → X (+5), T → Y (+5)

Similarly,

HKIJ $$\rightarrow$$ ?

H → M (+5), K → P (+5), I → N (+5), J → O (+5)

The code of HKIJ is MPNO.

Thus, correct option is (b).
