Final answer:
The HR Admin role is necessary for accessing the HR Properties module in ServiceNow, as it is tailored to managing HR settings and configurations.
Step-by-step explanation:
The minimum role required to access the HR Properties module is the HR Admin [sn_hr_core.admin]. In the context of ServiceNow human resources functionalities, different roles are assigned to control access levels within the system. The other listed options, such as HR Manager, LE Admin, and Admin, have their distinct responsibilities and permissions that may overlap or extend beyond the HR Properties module but the HR Admin role is specifically tailored to manage HR configurations and settings.
