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.
BLG:DHM
GMQ : IIW

​Given:

B L G : D H M

G M Q : I I W

Logic : "For each cluster, move the first letter 2 positions forward, the second letter 4 positions backward, and the third letter 6 positions forward in the alphabet."

B = B + 2 = D , L = L - 4 = H , G = G + 6 = M​

G = G+2 = I , M = M - 4 = I , Q = Q +6 = W

C N H : E J N 

C = C + 2 = E , N = N - 4 = J , H = H + 6 = N 

Thus, the correct answer is( c )  C N H : E J N​​
