Word formation from letters of COURAGEOUS Which ONE of the following words cannot be formed from “COURAGEOUS”, using each letter at most once?

Introduction / Context:
We must find the option that cannot be built from the source letter multiset.

Given Data / Assumptions:

• Source: COURAGEOUS ⇒ letters include C,O×2,U×2,R,A,G,E,S.
• Only one E is available.

Concept / Approach:
Check if any option needs a letter not present or a higher count than available.

Step-by-Step Solution:
“ARGUE”, “COURSE”, and “GRACE” fit the available letters.“SECURE” requires E×2; the source has E×1 ⇒ cannot be formed.

Verification / Alternative check:
Count E's explicitly: only one in COURAGEOUS.

Why Other Options Are Wrong:
They respect available letters and multiplicities.

Common Pitfalls:
Missing duplicate-letter needs like the second E in “SECURE”.

Final Answer:
SECURE
