Explanation:
account
The statement is:
"When provisioning an Azure Cosmos DB ______, you need to specify which type of API you will use." Options:
* account # Correct. When you create a Cosmos DB account, you must choose the API type (e.g., SQL API, MongoDB API, Cassandra API, Table API, Gremlin API). This decision defines the data model and query language. #
* container # A container is created inside a database (tables, collections, graphs) but does not determine the API type.
* database # Exists inside an account and inherits the API type from the account.
* item # Represents individual records/documents; not where the API is chosen.
Thus, the API choice is made at the account level.
The answer: account
* Azure Cosmos DB account overview
