Final answer:
[B] True DataSets can store their data in XML, allowing for data manipulation without a continuous connection to a database and providing interoperability across different systems.
Step-by-step explanation:
The question you've asked pertains to how DataSets store data and whether they use XML for storage. DataSet is a concept used in programming, and it's commonly associated with the .NET framework. The answer to your question is [B] True. A DataSet can store its data in XML format and it is designed to work disconnected from the original data source. This capability allows for easier data transfer between layers of an application and for data manipulation without a continuous connection to the database.
In practice, a DataSet can be serialized into XML for various purposes, such as saving the DataSet to a file, transmitting it across a network, or for interoperability with other systems that understand XML. XML is used as it provides a structured, human-readable format that is both platform and language-independent, which can be very useful in data exchange scenarios.
A DataSet is used to store and manipulate data in a tabular format in computer programs. While a DataSet can be serialized and persisted in various formats, including XML, it is not limited to XML as the only storage format. Other possible storage formats for a DataSet include JSON or a relational database.
