All of the above
All three statements (A, B, C) correctly describe differences between customization and configuration. Configuration makes standard settings available to all users and is essential for basic functionality, while customization allows individual customers to implement proprietary processes and is unpredictable/time-consuming. Configuration changes have predictable performance impacts, whereas customization effects are unpredictable. Option D correctly states all of the above.
