Answer: B

Explanation:

Amazon Elastic Map Reduce (EMR) is a web service that enables businesses, researchers, data analysts, and developers to easily and cost-effectively process vast amounts of data.

Amazon EMR historically referred to an Amazon EMR cluster (and all processing steps assigned to it) as a "cluster". Every cluster has a unique identifier that starts with "j-".

The different cluster states of an Amazon EMR cluster are listed below.

STARTING C The cluster provisions, starts, and configures EC2 instances.

BOOTSTRAPPING C Bootstrap actions are being executed on the cluster.

RUNNING C A step for the cluster is currently being run.

WAITING C The cluster is currently active, but has no steps to run.

TERMINATING – The cluster is in the process of shutting down.

TERMINATED – The cluster was shut down without error.

TERMINATED_WITH_ERRORS – The cluster was shut down with errors.
