You are a developer at a large corporation. You manage three GKE clusters. Your team’s developers need to switch from one cluster to another regularly on the same workstation. You want to configure individual access to these multiple clusters securely while following Google-recommended practices. What should you do?

A. Ask the developers to use Cloud Shell and run the gcloud container clusters get-credentials command to switch to another cluster. B. Ask the developers to open three terminals on their workstation and use the kubectl config set command to configure access to each cluster. C. Ask the developers to install the gcloud CLI on their workstation and run the gcloud container clusters get-credentials command to switch to another cluster. D. In a text file, define the clusters, users, and contexts. Email the file to the developers and ask them to use the kubectl config set command to add cluster, user, and context details to the file.
