Which of the following are standard attributes used in the Braze SDK?

The choice that includes first name, email, and date of birth is correct because these are indeed standard attributes that Braze collects and utilizes to personalize user engagement and messaging. First name and email are fundamental for identifying users and sending personalized communications, whereas date of birth allows for further customization of interactions based on age or special birthday offers.

While other selections may contain attributes that could be relevant to user profiles, they do not align with the core standard attributes recognized within the Braze SDK. For example, options that include location or purchase history can be important but are not classified as standard fields that Braze assumes are available for all applications. Similarly, attributes like date and time or last interaction are useful for analytics but do not fall under the umbrella of personal identifiers that Braze primarily associates with standard user profiles.
