Which of the following are examples of Content Patterns?

The correct answer identifies examples of Content Patterns, which are fundamental structures used to present and organize content within a mobile application effectively.

The choice that includes Blankslate, CardItem, and Chatmessage represents different ways to layout and display content. A Blankslate serves as an informative state to guide users when there’s no content to display, helping to indicate what actions they might take next. CardItem provides a visual way to group related information, often incorporating images and text within a defined card structure which enhances user engagement. Chatmessage is utilized to present messages in a conversation style, typically used in messaging applications, to create a familiar and intuitive user experience.

These components focus on how information is structured and presented to users, making them specific examples of Content Patterns as they are designed primarily to manage and display content to enhance user interaction. Other options, while containing some relevant items, do not exclusively encompass content organization in the same way, which is the primary characteristic of Content Patterns.
