Statement: Many school buses are fitted with CNG kits without following safety norms, leading to some fire incidents from electrical short circuits and endangering children. Courses of Action: I. The regional transport authority should immediately inspect all school buses with CNG kits for compliance. II. Schools must stop hiring buses with CNG kits entirely. III. Government should ban CNG use in school buses.

Introduction / Context:Safety lapses—not the fuel type per se—cause incidents. The response should enforce compliance rather than blanket bans that may be unnecessary and counterproductive.

Given Data / Assumptions:

• Some buses fitted CNG without observing guidelines.
• Fires linked to short circuits (electrical).

Concept / Approach:Immediate, universal compliance checks (I)—certification, wiring, venting, tank placement—are essential. Absolute prohibitions (II, III) ignore that compliant CNG is widely safe and environmentally beneficial; the problem is non-compliance.

Step-by-Step Solution:1) Conduct RTA audits; suspend non-compliant buses; mandate fixes (I).2) Train operators; periodic re-inspection.

Verification / Alternative check:Transport safety frameworks prefer compliance enforcement to fuel-type bans absent inherent risk.

Why Other Options Are Wrong:II/III overreach and reduce options without addressing root causes.

Common Pitfalls:Paper compliance without physical inspection.

Final Answer:Only I follows.
