Option A: Backing up container states is unrelated to runtime protection, which focuses on real- time threat detection and prevention.
Option B: Monitoring API calls is part of Kubernetes control plane security but is not directly related to runtime protection.
Option C: Image scanning for vulnerabilities is a pre-deployment task and does not pertain to runtime protection, which deals with active workloads.
Option D: Runtime protection focuses on safeguarding workloads by detecting and blocking malicious behavior during their execution. It provides continuous monitoring to secure active containerized environments.
