Continuous ignition is automatically provided when:

Continuous ignition is automatically provided when a thrust control malfunction is detected. This feature is crucial for maintaining engine stability and performance during abnormal conditions that could affect engine operation. In the event of a thrust control malfunction, activating continuous ignition ensures that the engine continues to operate smoothly, helping prevent unintended engine flameout due to factors like sudden thrust loss or spooling issues.

The other scenarios do not automatically trigger continuous ignition. For example, while selecting wing anti-ice on does require additional engine power, it doesn't necessitate continuous ignition. Similarly, low oil pressure may indicate maintenance issues but does not impact ignition directly, and turbulent air conditions may indeed pose challenges for the aircraft, yet they do not automatically engage continuous ignition either. Therefore, the correct choice indicates a specific operational safety protocol designed to manage engine reliability during critical moments.
