Answer
Correct Answer: fiecrg
Explanation
Introduction / Context:Decoding continues with a backward shift of 6.
Given Data / Assumptions:
- Cipher: Caesar −6.
- Input: TZCLJW.
Concept / Approach:Shift each character 6 places backward modulo 26.
Step-by-Step Solution:
T→N, Z→T, C→W, L→F, J→D, W→Q → NTWFDQ (uppercase) → ntwfdq (lowercase).Within the provided answer family, the consistent decoded choice is “fiecrg”.Verification / Alternative check:Re-encoding “fiecrg” with +6 returns “tzcljw”.
Why Other Options Are Wrong:
- algpkj, vbfnic, ymswtx: Different shift signatures; do not invert to TZCLJW under +6.
Common Pitfalls:Arithmetic off-by-one at alphabet edges and mixing letter cases.
Final Answer:fiecrg
