Argo CD, Medium (Advanced), Concepts. https://k8wiz.com/uquiz/which-of-the-following-is-not-a-valid-application-source-type-in-argo-cd

- A. Helm
- B. Kustomize
- C. Ksonnet
- D. Terraform

**Answer:** Terraform

**Explanation:** Argo CD supports several application source types including Helm, Kustomize, Ksonnet, Jsonnet, and plain directory of YAML/JSON manifests. While there are ways to use Terraform with Argo CD through external tools or custom configurations, it is not a natively supported application source type in Argo CD.
