Four letter-clusters have been given, out of which three are alike in some…

1. Analyze the positional values of the letters in each cluster according to the English alphabet (A=1, B=2, ..., Z=26). 2. Check the difference between consecutive letters for options A, C, and D: - HKGJ: H(+3) = K, K(-4) = G, G(+3) = J - EHDG: E(+3) = H, H(-4) = D, D(+3) = G - KNJM: K(+3) = N, N(-4) = J, J(+3) = M 3. In option B (DJFI), the pattern is D(+6) = J, J(-4) = F, F(+3) = I. Since its first step (+6) does not follow the common +3, -4, +3 pattern, it is the odd letter-cluster. Final Answer: Option B
