• B is correct answer, read below form google docs;

  This tutorial demonstrates how to migrate workloads running on a Google Kubernetes Engine (GKE) cluster to a new set of nodes within the same cluster without incurring downtime for your application. Such a migration can be useful if you want to migrate your workloads to nodes with a different machine type.

  Background A node pool is a subset of machines that all have the same configuration, including machine type (CPU and memory) authorization scopes. Node pools represent a subset of nodes within a cluster; a container cluster can contain one or more node pools.

  When you need to change the machine profile of your Compute Engine cluster, you can create a new node pool and then migrate your workloads over to the new node pool.

  To migrate your workloads without incurring downtime, you need to:

  Mark the existing node pool as unschedulable. Drain the workloads running on the existing node pool. Delete the existing node pool.
