Explanation:
The correct answer is C because the Kubernetes cluster can be resized using the gcloud command. Specifically, the command gcloud container clusters resize [CLUSTER_NAME] –node-pool [POOL_NAME] –size [SIZE] is used for this purpose. Option B is incorrect as the kubectl command cannot resize the cluster. Options A and D are also incorrect because manually editing the managed instance groups is not the recommended approach for resizing a Kubernetes cluster.
