Which service allows for the deployment and management of applications specifically for WorkSpaces?

The correct choice is the service that specifically facilitates the deployment and management of applications within the Amazon WorkSpaces environment. This service provides a streamlined way to package, distribute, and manage applications for virtual desktops.

Amazon WorkSpaces Application Manager (AWAM) allows administrators to configure the necessary applications for their WorkSpaces, enabling them to deliver a tailored desktop experience for users. It supports the creation of application bundles that can be deployed across multiple WorkSpaces, ensuring that users have access to the applications they need without requiring individual installations on each virtual desktop.

In contrast, the other services mentioned are designed for different use cases. Amazon AppStream 2.0 is focused on streaming desktop applications to any device but is not specific to WorkSpaces management. Amazon WorkDocs serves as a file storage and collaboration service rather than an application management framework. Amazon SES is an email sending service, which also has no relation to application deployment or desktop management within WorkSpaces. Hence, the choice that directly addresses the needs of managing applications specifically for WorkSpaces is Amazon WorkSpaces Application Manager.
