The correct answer is C.

A – Add additional nodes to your Container Engine cluster using the following command

gcloud container clusters resize CLUSTER_NAME –size 10

This is for a running cluster to resize an existing cluster to a provided size.

B – Add a tag to the instances in the cluster with the following command:

gcloud compute instances add-tags INSTANCE –tags enable-autoscaling max-nodes-10

First this is command for adding tags to instance, second simply adding tag will not automatically enable autoscaling.

C (Correct answer) – Update the existing Container Engine cluster with the following command:

gcloud container clusters update CLUSTER_NAME –enable-autoscaling –min-nodes=1 –max-nodes=10

This is the right command, please see “Enabling autoscaling for an existing node pool”

D – Create a new Container Engine cluster with the following command, and redeploy your application

gcloud container clusters create CLUSTER_NAME –enable-autoscaling –min-nodes=1 –max-nodes=10

This is the command enable autoscaling when you create the cluster not for running cluster. Please see “Creating a cluster with autoscaling”
