The correct answer is Offer an integrated analytics environment combining enterprise data warehousing with big data processing and data integration.

Azure Synapse Analytics is built as a unified platform that brings enterprise data warehousing together with big data processing and built in data integration. It combines dedicated and serverless SQL query engines with Apache Spark and pipeline orchestration so teams can ingest transform and analyze data in one integrated workspace. This unified design is what the bolded option describes and is the primary reason it fits the question.

Enable automatic collection of data from diverse sources for processing is incorrect because automatic collection and event ingestion are handled by services such as Azure Data Factory Event Hubs or other ingestion tools and not by a single definition of Synapse even though Synapse integrates with those tools.

Power BI is incorrect because Power BI is a separate service for reporting and visualization that can connect to Synapse but it is not the data warehousing and big data processing platform itself.

Act as a storage service for very large unstructured files is incorrect because storage of large unstructured data is the role of Azure Data Lake Storage or Blob Storage and Synapse is designed to process and query data stored there rather than serve primarily as raw object storage.
