What is the optimal technique for 2 developer to troubleshoot this?
Answer: A
Explanation:
The optimal technique for the developer to troubleshoot this issue is to add system.debug() statements to the code and use the Developer Console logs to trace the code. system.debug() is a method that prints a message to the debug log, which is a tool that captures information about the execution of the code. The Developer Console is an integrated development environment that allows the developer to access and analyze the debug logs. By adding system.debug() statements to the code, the developer can print the values of variables, the execution flow, and the errors and exceptions that occur during the trigger execution. By using the Developer Console logs, the developer can view and filter the debug messages and identify the cause of the issue. This way, the developer can troubleshoot the issue effectively and efficiently . Reference: [system.debug Method], [Debug Logs], [Developer Console]
