A company is using a single master node in an Amazon OpenSearch Service (Amazon Elasticsearch Service) cluster to provide a search API to its front-end applications. The company configured an automated process on AWS that monitors the OpenSearch Service cluster and automatically adds data nodes to scale the cluster, when needed. During the initial load testing, the system reacted to scaling events properly by adding data nodes, but every time a new data node is added, the company experiences a blue/green deployment that creates a disruption in service. The company wants to create highly available solution that will prevent these service disruptions.
Which solution meets these requirements?

A. Increase the number of OpenSearch Service master nodes from one to two.
B. Configure multi-zone awareness on the OpenSearch Service cluster.
C. Configure the OpenSearch Service cluster to use three dedicated master nodes.
D. Disable OpenSearch Service Auto-Tune and roll back its changes.
