For which components would the Online Conflict Resolution feature be enabled?

The Online Conflict Resolution feature is specifically designed to handle scenarios where multiple users are making changes to the same components in Salesforce. It is particularly applicable in the context of Apex Triggers and Apex Classes.

Apex Classes are a core part of Salesforce's programming model, allowing developers to define business logic in a structured way. When changes are made to Apex Classes, if conflicts arise due to simultaneous modifications, the Online Conflict Resolution feature facilitates collaboration among developers by managing those conflicts effectively.

Similarly, Apex Triggers also play a critical role as they are used to initiate actions in response to specific events, such as record creation or updates. Like Apex Classes, any modifications to triggers can lead to conflicts that need resolving to maintain the integrity of the application logic.

In contrast, the other choices either include components that do not require the Online Conflict Resolution feature, such as Layouts and Lightning Pages, which do not have the same level of technical complexity and collaborative usage seen with Apex components. These other options do not fully leverage the capabilities of Online Conflict Resolution because they focus on more declarative components or general UI elements rather than the programmatically intensive Apex components that are more likely to see concurrent modifications.

Thus, the identification of Apex Triggers and Apex Classes as the focus
