Crossplane is the CNCF project designed to extend Kubernetes with the ability to provision and manage cloud resources via Kubernetes-native APIs. Option B is correct because Crossplane lets developers use familiar Kubernetes manifests to request resources like S3 buckets, databases, or VPCs while abstracting provider-specific implementation details. Platform teams can define compositions and abstractions, providing developers with golden paths that include organizational guardrails.

Option A (Cluster API) is focused on provisioning Kubernetes clusters themselves, not cloud services. Option C (Helm) manages Kubernetes application deployments but does not provision external infrastructure. Option D (OpenTofu) is a Terraform fork that provides IaC but is not Kubernetes-native.

By leveraging Crossplane, platform teams achieve infrastructure as data and full GitOps integration, empowering developers to provision services declaratively while ensuring governance and compliance.
