Select the letter cluster pair that best represents a similar relationship to the one expressed in the pairs of letter clusters given below.

NGJ : OJE

MHK : NKF​​

Given: NGJ : OJE; MHK : NKF

Logic: Add 1, and 3 to the place values of the letters of the first and second letters respectively, and subtract 5 from the place value of the third letter.

NGJ : OJE $$\rightarrow$$ N + 1 = O; G + 3 = J; J - 5 = E

MHK : NKF $$\rightarrow$$​ M + 1 = N; H + 3 = K; K - 5 = F

Let's check the options:

Option (a): XHJ : YKF$$\rightarrow$$X + 1 = Y; H + 3 = K; J - 5 = E $$\neq$$ F​

Option (b): LMO : MOJ$$\rightarrow$$L + 1 = M; M + 3 = P $$\neq$$ O; O - 5 = J​

Option (c): JJK : KME$$\rightarrow$$J + 1 = K; J + 3 = M; K - 5 = F $$\neq$$ E​

Option (d): KNI : LQD$$\rightarrow$$K + 1 = L; N + 3 = Q; I - 5 = D

So, the correct answer is (d).
