Which of the following is not a valid option to analyze data using Azure Synapse Analytics?

Spark Pool is a valid Azure Synapse Analytics compute option that provides Apache Spark-based distributed processing for big data analytics.

Dedicated SQL Pool (formerly Azure SQL Data Warehouse) is a valid Synapse Analytics compute option that provides enterprise-scale data warehousing with massively parallel processing.

SQL Elastic Pool is a resource-sharing model within Azure SQL Database that allows multiple databases to share a combined pool of compute and storage resources. It belongs to Azure SQL Database, not Azure Synapse Analytics, and is therefore not a valid Synapse analysis option. The correct Synapse compute options are Spark Pool, Dedicated SQL Pool, and Serverless SQL Pool.

Serverless SQL Pool is a valid Synapse Analytics compute option that enables on-demand T-SQL querying of data in Azure storage without provisioning dedicated resources.
