In a certain code, P is written as "#", A as "%", C as "$", and E as "@". Using the same code, how is "PEACE" written?

Introduction / Context:
This is a direct symbol substitution problem. Each letter has a unique symbol mapping and the coded word is formed by replacing letters in order.

Given Data / Assumptions:

• P -> #
• A -> %
• C -> $
• E -> @
• Target word: PEACE

Concept / Approach:
Replace letters one by one according to the mapping without rearranging positions.

Step-by-Step Solution:
P -> #E -> @A -> %C -> $E -> @Therefore "PEACE" is "#@%$@".

Verification / Alternative check:
Check each symbol against the mapping; all positions agree.

Why Other Options Are Wrong:

• #@%@#: wrong at the 4th position (should be $ for C).
• #@#$@: wrong at the 3rd position (should be % for A).
• %#@$%: wrong order of letters; also ends with % instead of @.
• None of these: Not applicable as #@%$@ is valid.

Common Pitfalls:
Accidentally reordering letters or mixing the symbols for A and C since both are non-alphabetic and easy to confuse.

Final Answer:
#@%$@
