In a letter analogy BEH corresponds to KNQ. Using the same pattern of alphabetical shifts, FIL will correspond to which of the following letter groups?

Introduction / Context:
This question tests your ability to recognise consistent alphabetical shifts. A three letter group BEH is related to KNQ by a constant forward movement in the alphabet. You must first identify that shift and then apply it to the group FIL to find its corresponding code.

Given Data / Assumptions:

• Original letters: B, E, H
• Coded letters: K, N, Q
• Target original group: F, I, L
• All shifts are within the standard English alphabet and are uniform for this pair.

Concept / Approach:
The standard way to handle such analogies is to assign each letter its position in the alphabet, compute the difference from original to coded letter for each position, and check if a constant shift has been applied. If so, we can apply the same shift to the new letter group to generate the correct coded group.

Step-by-Step Solution:

Verification / Alternative check:
Verify that ORU appears in the options and make sure no other choice can be obtained by a constant shift of +9 from FIL. Recheck the original mapping BEH to KNQ to confirm that the same rule is applied consistently. Since all three letters match the shift, ORU is uniquely correct.

Why Other Options Are Wrong:

• ONM does not fit a single constant shift from FIL and breaks the pattern in at least one position.
• NLJ would require different adjustments for each letter and is inconsistent with the clear plus nine rule.
• OMK is derived by a mix of shifts and does not respect the uniformity seen in the original pair.
• PRS has different starting letters and cannot be generated from FIL by a constant movement.

Common Pitfalls:
Some candidates focus on rough letter similarity and choose options that look visually close, for example starting with O. However, the key to such questions is the exact numerical shift, not approximate shape. Always convert letters to numbers, check the shift, and then apply that shift carefully to the new group.

Final Answer:
Following the same pattern, FIL is coded as ORU.
