Final answer:
The default value for Category in an Incident form depends on the specific incident management system being used and its configuration. 'Inquiry' or 'None' are common defaults, but one should check the system's documentation or settings for the accurate default value.
Step-by-step explanation:
The default value for Category in an Incident form within most incident management systems such as IT Service Management (ITSM) tools is typically set to a generic option.
However, without specific context as to which incident management system or platform is being referenced, it's not possible to give a definite answer. In some systems, the default may be set to general categories such as 'Inquiry' or 'None', to prompt the user to select the most appropriate category for the incident. It's important to consult the specific documentation or the configuration of the incident management system in question to determine the default setting for the Category field.
