Explanation:
Spark's execution/deployment modes include Client mode (driver runs on the client machine), Cluster mode (driver runs inside the cluster), and Local mode (single-machine execution). However, Standard mode (option C) does not exist as a valid deployment mode in Spark. The confusion might arise from terms like 'Standalone mode,' which refers to Spark's built-in cluster manager, not a deployment mode. Thus, option C is the correct answer as it is not a valid execution/deployment mode.
