Option A: Excluding all system processes creates a significant security risk and is not an effective way to manage false positives.
Option B: Editing the existing policy is sufficient and does not require deletion. Recreating policies unnecessarily increases administrative overhead.
Option C: Lowering the sensitivity of "Exploit Detection" can help reduce false positives by adjusting the thresholds for detecting potential threats. This action retains proactive protection while improving alert accuracy.
Option D: Policy priority affects which policy is applied when multiple policies overlap but does not address false positives within a policy.
