The Malfunction Indicator Lamp (MIL) is used to indicate which type of faults?

Explanation:
The Mil signals problems that affect the vehicle’s emissions. It lights up when the onboard diagnostics system detects a fault in the engine management or emissions control systems that could cause higher emissions or fail an emissions test. That focus on emissions makes it the best choice for describing what the MIL indicates. It isn’t meant to flag battery issues or transmission faults, which have different warning indicators, and it isn’t used for every engine fault outside the emissions domain.
