What types of permissions can be set for Ticket Forms?

The correct answer focuses on field visibility options and permissions based on agent roles, which are crucial for controlling access to different ticket forms within Zendesk. This capability allows administrators to define which fields are visible and editable depending on the roles assigned to agents. For instance, certain sensitive fields could be restricted to higher-level agents while others remain accessible to more junior staff. This hierarchical approach enhances security and ensures that agents only interact with the information pertinent to their responsibilities.

The other options do not accurately encompass the permissions associated with Ticket Forms. Required or optional fields pertain to how information is collected but do not specifically address permissions. Custom ticket IDs and categorization relate to tracking tickets but do not directly confer permission settings for agents. Field types for formatting ticket descriptions refer to the presentation of information rather than controlling access or visibility based on user roles.
