Statement: "If you see any street lights on during the day, or notice electricity pilferage, please inform us." — a notice by NDPL to the public.\nAssumptions:\nI. Watching TV together and using a single fan/cooler/AC will help conserve electricity.\nII. Power generation is limited; joint conservation efforts can help maintain reliable electricity supply.

Introduction / Context:
The notice asks citizens to report waste (street lights on during daylight) and theft (pilferage). This is a demand-side management and loss-reduction appeal. We test which assumptions are necessary for the appeal to be meaningful.

Given Data / Assumptions:

• Request: report waste/theft to the utility.
• Goal: conserve resources and improve supply reliability.
• I: household co-use tips (watching TV together, sharing cooling) save power.
• II: generation is constrained; collective conservation improves reliability.

Concept / Approach:
The notice’s logic rests on the system-level premise that power is limited and that reducing waste/theft contributes to stable supply. Household tips (I) are not part of this notice; they may be true but are not presupposed by the request to report specific issues.

Step-by-Step Solution:
1) Without II, asking for public vigilance would lack a system benefit rationale.2) I is extraneous; the notice focuses on reporting anomalies, not household behavior protocols.3) Hence, only II is implicit.

Verification / Alternative check:
Utilities worldwide solicit public reports on outages, theft, or wastage precisely because reducing non-technical/technical losses helps grid stability.

Why Other Options Are Wrong:
I adds a different conservation mode not referenced; options including I therefore overreach.

Common Pitfalls:
Generalizing from conservation tips to the specific call for reporting abnormal situations.

Final Answer:
Only assumption II is implicit.
