What describes coarse-grained components in Visualforce?

1. They add minimal functionality to a page.

2. They provide a large amount of functionality in one component.

3. They require multiple lines of markup.

4. They are focused on a single functionality.

The correct answer is: They provide a large amount of functionality in one component.

Coarse-grained components in Visualforce refer to components that encapsulate a substantial amount of functionality within a single unit. These components are designed to handle larger, more complex tasks, allowing developers to implement significant features with minimal effort on a page. By grouping multiple functionalities together, these components promote reuse and ensure consistency across various pages. The essence of coarse-grained components is their ability to simplify the code structure. By leveraging such components, developers can manage complexity more effectively, reducing the amount of repetitive markup needed throughout the application. This approach contrasts with fine-grained components, which focus on smaller, single functionalities and often require more lines of markup for implementation, thereby increasing the potential for redundancy and making the codebase harder to maintain. Understanding the role of coarse-grained components is crucial for efficient Visualforce page development and effective management of Salesforce applications.
