Which of the following is a characteristic of the Lightning Component Framework?

1. It has an event-driven architecture.

2. It works with existing Visualforce pages.

3. It includes responsive components.

4. It uses XML as its data format.

The correct answer is: It has an event-driven architecture.

The Lightning Component Framework is designed with an event-driven architecture, which allows for a more dynamic and responsive user interface. This architecture facilitates communication between components, enabling them to respond to user interactions and data changes seamlessly. By using events to communicate, components can be decoupled from one another, promoting reusability and maintainability in application development. Other characteristics like responsiveness and compatibility with Visualforce pages are important in their own right, but they do not specifically define the foundational architectural approach of the Lightning Component Framework. Instead, the event-driven nature allows developers to create components that react to various stimuli in real-time, enhancing the overall user experience. Additionally, while data formats such as JSON are used in the framework, the choice of XML as a data format does not accurately characterize the Lightning Component Framework itself, which primarily leverages JavaScript for functionality. Thus, the event-driven architecture stands out as a defining feature of the framework.
