Which component could be a reason for choosing manual conflict resolution over automatic methods?

Choosing manual conflict resolution over automatic methods is often essential when dealing with complex Apex classes. This is because Apex classes may contain intricate business logic, multiple dependencies, and careful control flow that must be thoroughly understood and potentially modified to ensure that the merged code behaves as expected. Automatic conflict resolution might not accurately capture the nuances of these classes, leading to bugs or unexpected behaviors.

When conflicts arise in simple changes, such as layout modifications or basic configuration settings, these are typically easier to resolve automatically since they usually don't involve complicated logic or multiple integrations. Similarly, standard reports are generally straightforward and may not require extensive manual intervention to resolve conflicts.

In the case of complex Apex classes, carefully analyzing the specific changes is necessary to maintain the integrity of the code, thereby justifying the choice for manual intervention in conflict resolution processes.
