Decode the symbol string to letters using the given letter→symbol code. Code: A→@, C→#, D→$, E→%, M→^, S→&, N→*, R→α, Q→β, V→γ, L→δ Given symbols: ^ @ α γ % δ

Introduction / Context:Here a fixed set of letters is encoded as symbols. We must invert the mapping to recover the original word.

Given Data / Assumptions:

• A→@, C→#, D→$, E→%, M→^, S→&, N→*, R→α, Q→β, V→γ, L→δ.
• Symbol string: ^ @ α γ % δ.

Concept / Approach:Translate each symbol back to its letter using the inverse of the given table.

Step-by-Step Solution:

Verification / Alternative check:Re-encode MARVEL using the forward code to obtain the same symbol sequence.

Why Other Options Are Wrong:

• MASTER, MENACE, MASQUE: At least one letter in each does not match the decoded letters at a specific position (e.g., the third position must be R due to α).

Common Pitfalls:Reading γ as G; it encodes V per the table.

Final Answer:MARVEL
