Which statement is correct regarding Salesforce APIs for a native mobile application?

The statement about the REST API supporting OAuth is correct because OAuth is a widely used authentication standard that provides secure access to resources and is especially useful in mobile applications. In the context of a native mobile application, being able to utilize OAuth with the REST API allows developers to securely authenticate users, manage access tokens, and ensure that any API calls made on behalf of the user are authorized. This is critical for maintaining user security and ensuring that sensitive data is protected while interacting with Salesforce services.

The REST API's support for OAuth enables seamless integration with third-party systems and facilitates a better user experience, as users can log into the mobile app through their existing accounts without needing to share credentials. This capability is particularly important in native mobile applications where security and user authentication must be handled carefully.
