APR Oil Temperature limit is?

Explanation:
Oil temperature limits define how hot the oil can get and for how long you may operate at that high temperature. This protects the lubrication system from breakdown and excessive wear as the engine or APU works harder. In this case, the APR oil temperature limit is 163°C for 15 minutes. This means you can allow the oil to reach up to 163°C and stay there for up to 15 minutes, but you should not exceed that temperature or extend the duration beyond the specified time. It provides a window for short periods of higher demand, after which you should take action to cool the system or reduce power to stay within safe operating limits. The other options don’t match the documented limit: they propose different temperatures or shorter/longer durations that aren’t the defined rating.
