Situation–Reaction (Honesty in a transaction)\nAfter a purchase, the shopkeeper returns ₹100 extra to you by mistake. What should you do?

Introduction / Context:
Situation–Reaction items test ethical judgment and practical responsibility in everyday scenarios. Here, you received ₹100 extra due to the shopkeeper’s oversight.

Given Data / Assumptions:

• You made a purchase, and change was mistakenly overpaid to you by ₹100.
• No hardship or coercion is described; the overpayment is an error.
• You have an immediate opportunity to correct it.

Concept / Approach:
Honesty and fairness are core civic values. Accepting undue gain from another’s mistake constitutes unjust enrichment. Correct action is to promptly return the excess and clarify the error.

Step-by-Step Solution:

Verification / Alternative check:
Consider role reversal: If you were underpaid, you would expect restitution. Ethical reciprocity supports returning the extra change.

Why Other Options Are Wrong:
A, B, and C normalize misuse of someone else’s money. “None of these” is unnecessary because option D states the proper action explicitly.

Common Pitfalls:
Rationalizing a “small” dishonest gain or assuming a big store “won’t miss it.”

Final Answer:
return the extra money to the shopkeeper
