What are the two main components of the TraX interface?

The TraX interface is designed to facilitate the management of both travel planning and expense reporting, making option A the correct choice. Travel planning encompasses the tools and features that allow users to organize and book travel arrangements efficiently, which includes researching locations, selecting accommodations, and arranging transport. Expense reporting is equally vital, as it enables users to document and submit expenses incurred during travel, ensuring compliance with regulations and facilitating reimbursement processes. Together, these components streamline the overall travel experience for users, allowing them to manage their travel needs comprehensively within a single platform.

In contrast, the other options focus more narrowly on specific activities involved in travel, rather than encompassing the full range of functionalities provided by TraX. For example, while travel authorization and ticket booking are relevant, they do not fully capture the overarching capabilities of the interface. Similarly, flight arrangements and ground transportation, as well as expense reporting and payment processing, target only segments of the travel management process. Therefore, the combination of travel planning and expense reporting best represents the dual primary functions of the TraX interface.
