What will be the beginning of the log filename when specific code executes and the log level is set to info?

The beginning of the log filename when specific code executes and the log level is set to info will start with "custom-xyz." This is aligned with how Salesforce B2C Commerce organizes log files, particularly under the custom logging framework.

When you set a log to a specific level, like 'info,' the naming convention generally incorporates a prefix that identifies the log's context. "Custom" indicates that the log is related to custom code or implementation, and "xyz" serves as a specific identifier within that context. Therefore, "custom-xyz" is a logical and systematic way to name the log files generated during the execution of the code when the log level is set to info, ensuring that developers can easily identify and manage logs associated with custom functionality in their applications.

In contrast, the other options don't align with the standardized naming practice in Salesforce logging structure, either by starting with a different prefix or lacking the appropriate context for information logging.
