The correct answer is Azure Synapse Analytics.

Azure Synapse Analytics is a fully managed cloud data warehouse and analytics platform that can ingest and consolidate data from multiple sources and enable advanced analytics and reporting. It provides dedicated and serverless SQL pools for data warehousing, integrates with data ingestion and orchestration services, and connects to reporting tools for business intelligence.

Azure Data Factory is incorrect because it is a data integration and orchestration service used to move and transform data and not a data warehouse that stores and queries consolidated data for analytics.

Azure Analysis Services is incorrect because it provides semantic modeling and analytical processing for BI workloads and does not serve as the underlying fully managed cloud data warehouse for large scale storage and query processing.

Azure Machine Learning is incorrect because it focuses on building training and deployment pipelines for machine learning models and it is not a service for consolidating multiple data sources into a managed warehouse for reporting.
