Which of these statements about data sources is true?

Power Apps utilizes connectors to interact with various external data sources, making option C the accurate statement. Connectors serve as the bridge between Power Apps and a multitude of services, databases, and applications, whether they are on-premises or cloud-based. This capability enables users to not only read data from these sources but also write back to them, provided that the specific data source allows such actions.

The versatility of Power Apps is enhanced through this feature, allowing for a dynamic integration of data from services like SharePoint, Salesforce, Microsoft Dataverse, SQL Server, and even RESTful APIs, among others. This adaptability is essential for building applications that require real-time data interaction and comprehensive data management.

In contrast, the other statements inaccurately represent the data handling capabilities within Power Apps, focusing instead on limiting the data to local storage or an internal database, which does not reflect the platform's extensive integration potential. Power Apps empowers users to leverage external data effectively, providing a robust environment for app development.
