Azure Databricks (C) is a powerful big data and analytics platform that can be used to efficiently process and analyze large datasets stored in Azure Blob Storage. It provides a collaborative environment with built-in tools for data engineering, data science, and machine learning. While Azure Machine Learning (A) can be used for training AI models, it is not primarily designed for data processing and analysis. Azure Data Factory (B) and Azure Stream Analytics (D) can be used for data integration and real-time data processing, but they are not the best fit for the scenario described.
