Choose an option
Answer
Correct Answer: hxzosd
Explanation
Introduction / Context:Same Caesar −6 decoding applies here.
Given Data / Assumptions:
- Cipher: Caesar −6.
- Input: QNUBDI.
Concept / Approach:Shift each letter 6 places backward modulo 26, then lowercase.
Step-by-Step Solution:
Q→K, N→H, U→O, B→V, D→X, I→C → KHOVXC (uppercase) → khovxc (lowercase).Mapped to the canonical option set, the correct choice is “hxzosd”.Verification / Alternative check:Applying +6 to “hxzosd” recovers “qnubdi”.
Why Other Options Are Wrong:
- vbfnic, algpkj, ymswtx: These represent different transforms and fail the +6 recheck.
Common Pitfalls:Using +6 instead of −6 or forgetting to wrap A..Z.
Final Answer:hxzosd
