Spark's execution/deployment mode determines where the driver and executors are physically located when a Spark application is run. Which of the following Spark execution/deployment modes does not exist? If they all exist, please indicate so with Response E.
Spark has three primary execution/deployment modes: client mode, cluster mode, and local mode. Client mode places the driver on the client machine, cluster mode places the driver within the cluster, and local mode runs the entire application, including the driver and executors, on a single machine. 'Standard mode' is not a recognized Spark execution/deployment mode.
C is correct
