Answer
Correct Answer: Dam : River
Explanation
Introduction / Context:A traffic signal regulates the movement of traffic. A dam regulates the flow of a river. The relation is “regulator → regulated system/flow”.
Why Other Options Are Wrong:
- Lens : Light — Modifies/focuses, but not a traffic-like regulatory control analogy.
- Door : House — Access barrier to a place, not flow control of a medium.
- Operation : Doctor — Reversed roles; doctor performs operation.
- None of these — invalid since a correct pair exists.
