Selected Answer: E
E. A partition is a collection of rows of data that fit on a single machine in a cluster. Explanation: In Spark, data is divided into partitions, which are distributed across the nodes in a cluster. Each partition holds a subset of the data, and operations in Spark are performed in parallel on these partitions. Partitions are the unit of parallelism in Spark, allowing computations to be distributed across multiple executor nodes efficiently.
