Final answer:
The statement is true; the DataReader component is indeed used to retrieve read-only and forward-only data from a data source, optimizing data retrieval for performance. The statement is [B] True.
Step-by-step explanation:
The statement that the DataReader component is used to get the read-only and forward-only data from the data source is True.
The DataReader in .NET frameworks such as ADO.NET provides a way of reading a forward-only stream of data rows from a data source. This is often used in scenarios where performance is critical as it's designed to load data as quickly as possible without the overhead of tracking changes or allowing navigation backwards.
The DataReader component in ADO.NET is used to provide a fast and efficient way to retrieve data from a data source. However, it does not necessarily mean that the data is read-only and forward-only.
The DataReader object can be used to retrieve data that is read-only and forward-only, but it can also be used to retrieve data that is not.
