What is the common consequence of disabling a fuel monitoring system?

Disabling a fuel monitoring system significantly increases the risk of leaks because these systems are designed to track fuel levels and detect any irregularities or changes that may indicate a leak. When a monitoring system is operational, it continuously assesses the integrity of the fuel storage tanks and related infrastructure, which helps identify potential leaks before they become serious issues. Without this monitoring, leaks may go undetected for long periods, leading to environmental contamination and safety hazards.

The other options do not accurately represent the consequences of disabling a fuel monitoring system. Lower fuel efficiency is not a direct result of disabling monitoring, and there would be no improvement in fuel tracking since the system would be inactive. Additionally, while disabling such a system might temporarily reduce monitoring costs, it does not present a long-term financial advantage due to the potential for costly environmental damage and regulatory fines resulting from undetected leaks.
