Which one of the following is NOT a type of Visual Task Board?

ServiceNow provides three primary types of Visual Task Boards (VTBs) for managing tasks. These are Guided (also known as Data Driven), Flexible, and Freeform boards. Guided boards automatically generate lanes based on field values (e.g., State). Flexible boards offer a combination of field-driven and freeform lanes. Freeform boards allow users to create custom lanes and manually add any task. "Feature" is not a recognized, standard type of Visual Task Board on the ServiceNow platform.

B. Guided boards: This is a standard VTB type where lanes are automatically created from the values of a specific field, such as 'State' or 'Priority'.
C. Flexible: This is a standard VTB type that combines the features of guided boards with the ability to add additional freeform lanes.
D. Freeform: This is a standard VTB type that allows users to create their own lanes and manually add any task record to them.

1. ServiceNow Product Documentation: Visual Task Boards. In the section "Types of visual task boards," the documentation explicitly lists and describes the three valid types: "Freeform boards," "Data driven boards (Guided boards)," and "Flexible boards." The term "Feature board" is not mentioned as a VTB type.

2. ServiceNow Developer Documentation: Visual Task Boards. This resource also outlines the creation and use of the three core VTB types, reinforcing that Guided, Flexible, and Freeform are the officially supported classifications.
