Explanation

IBM Cloud Kubernetes Service (IKS) supports auto-scaling with custom metric-based policies through its integration with the Kubernetes Horizontal Pod Autoscaler (HPA) and custom metrics adapters, allowing you to scale workloads based on application-defined metrics beyond just CPU and memory. IBM Cloud Object Storage (B) is a storage service with no compute scaling capabilities. IBM Cloud Databases (C) is a managed database offering that handles its own internal scaling but does not expose policy-based auto-scaling on custom metrics to users. IBM Cloud Virtual Servers (D) does support some scaling, but it operates at the VM level without the flexible, custom-metric policy framework that Kubernetes provides.

Memory tip: Think "K for Kubernetes, K for Knobs" - Kubernetes gives you the most knobs to tune scaling behavior, including custom metrics, making it the go-to answer whenever exam questions involve flexible or custom auto-scaling policies.
