The correct answer is A. Task.
Explanation: In the Spark execution hierarchy, the most granular level is the task. A task represents a unit of work that is executed on a partitioned portion of the data in parallel. Tasks are created by the Spark driver program and assigned to individual executors for execution. Each task operates on a subset of the data and performs a specific operation defined by the Spark application, such as a transformation or an action.
