You are a developer at a large corporation. You manage three Google Kubernetes Engine clusters on Google Cloud. Your team’s developers need to switch from one cluster to another regularly without losing access to their preferred development tools. You want to configure access to these multiple clusters while following Google-recommended best practices. What should you do?

A. Ask the developers to use Cloud Shell and run gcloud container clusters get-credential to switch to another cluster. B. In a configuration file, define the clusters, users, and contexts. Share the file with the developers and ask them to use kubect1 contig to add cluster, user, and context details. C. Ask the developers to install the gcloud CLI on their workstation and run gcloud container clusters get-credentials to switch to another cluster. D. Ask the developers to open three terminals on their workstation and use kubect1 config to configure access to each cluster.
