- B. Using kubectl apply with static manifests
- C. Using the cert-manager operator
- D. Using the cert-manager installer script

**Answer:** Using the cert-manager installer script

**Explanation:** Using the cert-manager installer script is not a valid way to install cert-manager as there is no official installer script. The valid installation methods include using Helm, using kubectl apply with static manifests from the cert-manager releases, and using the cert-manager operator (though this is less common).
