The correct answer is D. Time Administrator Home.

In Workday Time Tracking, Time Administrator Home is the app designed to provide administrators with a centralized workspace for managing time tracking activities. It displays cards that surface commonly used tasks, reports, alerts, and administrative actions, making it easier for time administrators to access the most relevant tools from one place. This home page is intended to improve efficiency by organizing frequent Time Tracking functions into a single operational hub.

The other options are not apps that provide a card-based administrative home experience. All Time Entry Templates is a report or task used to review configured templates, not a central home app. View Worker's Time Eligibility is a worker-specific report used to review which time tracking components apply to a worker. View Worker's Time Eligibility by Organization is also a reporting function, focused on reviewing eligibility across organizations rather than serving as a dashboard.

Because the question specifically asks for an app that offers a central location for cards showing frequently used Time Tracking tasks and reports, Time Administrator Home is the only option that fits that description. It is the main administrative landing area for ongoing monitoring and action in Workday Time Tracking.

Therefore, the correct answer is D. Time Administrator Home.
