Explanation
To deploy a database resilient cluster engine across three Nutanix clusters, the database engine must support high availability (HA) and distributed deployment capabilities that NDB can manage across multiple clusters. PostgreSQL is the only database engine listed that NDB supports for a resilient cluster deployment across multiple clusters. NDB's HA features for PostgreSQL include automated failover, replication, and data consistency across geographically distributed clusters, making it suitable for a three-cluster scenario. This is achieved through PostgreSQL's built-in streaming replication and NDB's orchestration of HA policies.
