Multiple Choice

If no oil pressure is indicated, the engine must be shut down immediately and the fire garage contacted.

Explanation:
When oil pressure is zero, the engine is not being lubricated. Without lubrication, metal components rub together, leading to rapid wear, overheating, and potential catastrophic damage such as bearing seizure. Because the consequences can escalate quickly, the safest action is to shut the engine down immediately to prevent further harm. After securing the engine, contact the fire garage so maintenance can diagnose and repair the cause—whether it’s the oil pump, supply lines, or oil level gauge. Waiting or continuing to run would greatly increase the risk of severe engine damage, so the other options don’t fit.
