In this letter analogy question, select the related group of letters from the given alternatives to complete the pattern: XVT : RPN :: LJH : ?

Introduction / Context:
This letter analogy question requires you to discover a consistent backward shift in alphabet positions. The given pair XVT and RPN illustrates a pattern, and you must apply the same pattern to the letters LJH to choose the correct answer from the options. Such questions are standard in verbal and non verbal reasoning and test your comfort with systematic letter shifting.

Given Data / Assumptions:
The first pair is XVT and RPN.
The second starting group is LJH.
The options are FDB, ECA, KIG, QOM, and NJL.
We assume that the relationship between XVT and RPN is derived from a constant backward movement in the alphabet, and that the same shift must be applied to LJH.

Concept / Approach:
In letter analogies, we typically convert each letter to its alphabet position and try to find either a fixed addition or subtraction. Here, the letters in RPN appear earlier in the alphabet than the corresponding letters in XVT, suggesting a negative shift. Once we determine the exact amount by which each letter moves backward, we apply that amount to each letter in LJH and see which option matches the resulting group.

Step-by-Step Solution:
Step 1: Write the positions for XVT. X = 24, V = 22, T = 20.Step 2: Write the positions for RPN. R = 18, P = 16, N = 14.Step 3: Compute the shifts: 24 to 18 is minus 6, 22 to 16 is minus 6, and 20 to 14 is minus 6.Step 4: Thus, the transformation from XVT to RPN is subtracting 6 from each letter position.Step 5: Now write positions for LJH. L = 12, J = 10, H = 8.Step 6: Subtract 6 from each: 12 minus 6 = 6 (F), 10 minus 6 = 4 (D), and 8 minus 6 = 2 (B).Step 7: The resulting group is FDB, which matches one of the options exactly.

Verification / Alternative check:
We can verify by counting backward in the alphabet. From L, moving back six steps gives K, J, I, H, G, F. From J, moving back six steps gives I, H, G, F, E, D. From H, moving back six steps gives G, F, E, D, C, B. This direct counting confirms the transformation LJH to FDB with a uniform minus 6 shift. As this mirrors the minus 6 shift from XVT to RPN, the rule is consistent and the answer is reliable.

Why Other Options Are Wrong:
Option ECA would result from a minus 7 shift for some letters and a different shift for others, so it fails to maintain the consistent minus 6 pattern.
Option KIG is very close to the original LJH and corresponds to a small backward shift, not the full minus 6 seen in the example pair.
Option QOM belongs to a different region of the alphabet and does not arise from subtracting 6 from each of L, J, and H.
Option NJL seems to use a mixture of forward and backward shifts and therefore does not implement a simple consistent subtraction rule.

Common Pitfalls:
Candidates sometimes look only at the first letter and find an approximate shift, then choose an option without verifying the remaining letters. This is risky because exam setters intentionally include distractor options that partly match the pattern. A disciplined approach is to calculate the exact numeric shift for each letter of the first pair and then apply that shift to every letter of the new group. This ensures that your answer satisfies the rule fully rather than partially.

Final Answer:
Hence, using the same minus six shift seen in XVT : RPN, the correct completion of the analogy LJH : ? is FDB.
