The process described in the question is known as the Map phase, where BigData is broken into smaller chunks, and each processor searches its assigned set for a specific piece of information. The Map phase is usually the first step in the MapReduce framework, where data is mapped, sorted, and partitioned before proceeding to the Reduce phase for analysis. Therefore, Option D is the correct choice.
