How can a Salesforce Administrator grant access to the Salesforce mobile app for external user profiles?

Granting access to the Salesforce mobile app for external user profiles primarily involves ensuring that those profiles have the necessary permissions and capabilities enabled. The correct choice, which involves granting the "API Enabled" profile permission, is crucial because the Salesforce mobile app utilizes API calls to communicate with Salesforce data. If the external user profile does not have this permission enabled, users will not be able to access the mobile app effectively, as it relies on API access to function properly.

This permission is especially important for external users, as it allows them to interact with Salesforce data through the mobile interface securely. By ensuring that the profile has this enabled, the administration can facilitate a seamless experience for external users, allowing them to take advantage of the features offered by the mobile application.

The other options, while related to user access and permissions, do not specifically address mobile app access in the way that the "API Enabled" permission does. Some may involve broader concepts or additional licenses which are not directly tied to enabling mobile access. Hence, focusing on granting the correct profile permission is essential for appropriately enabling your external users to utilize the Salesforce mobile app.
