Situation–Reaction: While riding a scooter, you witness two youths on a motorcycle snatch a woman's gold chain and speed away. What is the most responsible immediate action?

Introduction / Context:
This scenario tests public safety judgment. The observer witnesses a violent property crime in progress. The key decision is whether to pursue, ignore, or escalate safely to authorities.

Given Data / Assumptions:

• A chain snatching has just occurred.
• You are on a scooter; offenders are on a motorcycle and fleeing.
• There may be risk to you, the victim, and bystanders if you engage in pursuit.

Concept / Approach:
Priority is life and safety, then evidence preservation and rapid notification. Civilians should avoid risky pursuit that can lead to road accidents or escalation. Timely, accurate reporting greatly improves police response and case solvability.

Step-by-Step Solution:

Verification / Alternative check:
Police interception relies on prompt, specific information. Pursuit by untrained civilians increases risk without guaranteeing success.

Why Other Options Are Wrong:
(a) Empathy is good but insufficient. (b) Pursuit is unsafe and can obstruct police. (d) Passivity undermines justice. (e) Mob pursuit increases risk and liability.

Common Pitfalls:
Heroic overconfidence; giving vague descriptions; contaminating evidence.

Final Answer:
Call police immediately and facilitate a formal report with precise details (Option C).
