In the given letter cluster pairs, the first letter cluster is related to the second letter cluster following a certain logic. Study the given pairs carefully, and from the given options, select the pair that follows the same logic.
QJD : TMG
GMS : JPV

Given: QJD : TMG; GMS : JPV

Logic: For each pair, add 3 to the place value of the letters of the first letter cluster to get the second letter cluster.

QJD : TMG $$\rightarrow$$ Q + 3 = T; J + 3 = M; D + 3 = G $$\rightarrow$$ TMG

GMS : JPV $$\rightarrow$$ G + 3 = J; M + 3 = P; S + 3 = V $$\rightarrow$$ JPV

Let's check the options:

Option a: MYO : PQJ; MYO $$\rightarrow$$​ M + 3 = P; Y + 3 = B; O + 3 = R $$\rightarrow$$ PBR $$\neq$$ PQJ​

Option b: NIH : SXB; NIH $$\rightarrow$$​ N + 3 = Q; I + 3 = L; H + 3 = K $$\rightarrow$$ QLK $$\neq$$ SXB​

Option c: RPH : USK; RPH $$\rightarrow$$​ R + 3 = U; P + 3 = S; H + 3 = K $$\rightarrow$$ USK​

Option d: AWL : ZDT; AWL $$\rightarrow$$​ A + 3 = D; W + 3 = Z; L + 3 = O $$\rightarrow$$ DZO $$\neq$$ ZDT

Thus, the correct answer is (c).
