Which of the following is a common software solution used by help desks for ticketing?

Zendesk is recognized as a common software solution specifically designed for help desks and customer support operations, particularly for ticketing purposes. It provides a platform for managing and tracking customer inquiries, support requests, and various issues that need resolution. By utilizing a ticketing system, help desks can streamline their processes, organize requests by priority, and ensure timely responses to customers.

In contrast, Microsoft Word is primarily a word processing program, and while it can be useful for creating documents related to help desk operations, it does not offer the specialized functionalities needed for ticket management. Adobe Photoshop is a graphic design software, which is not relevant to the ticketing process within help desk environments. Google Chrome, being a web browser, facilitates access to various online applications including ticketing systems, but does not function as a ticketing solution itself. Thus, Zendesk stands out as the appropriate choice for help desk ticketing activities.
