Answer :
Final answer:
Hitting a governor limit in Salesforce during an Apex transaction initiated from a Visualforce page will roll back any uncommitted changes. To minimize the risk of hitting these limits, developers must write efficient, bulkified code and use error handling. So, the correct option is B. Any changes up to the error are rolled back.
Explanation:
When a Visualforce page calls an Apex controller, which then calls another Apex class, and a governor limit is reached, all changes made up to that point are rolled back. This is because Salesforce enforces strict governor limits to ensure that resources are used efficiently and that one process does not monopolize shared resources on their multitenant platform.
Governor limits control the amount of resources or operations that can be consumed or performed in a given context. When a limit is exceeded, a runtime exception is thrown, which if not caught, rolls back all database changes to maintain data consistency. However, if a savepoint is set and the exception is caught, it is possible to roll back to the specified savepoint, therefore having partial changes saved up to that point.
To prevent hitting governor limits, developers should follow best practices such as using bulkified code and efficient SOQL queries, keeping track of limits with the Limits class methods, and writing robust error handling that captures and treats exceptions gracefully.
