Explanation:
The correct answer is to use the gcloud container clusters resize command for resizing your Kubernetes cluster, as specified in the GCP documentation. This command allows you to adjust the number of nodes in your cluster efficiently. The kubectl command does not support cluster resizing, making option B incorrect. Manually editing the managed instance group or enabling autoscaling (options A and C) are not the recommended methods for resizing a Kubernetes cluster directly.
