The layer responsible for managing the user interface and graphics in iOS is Cocoa Touch. This layer provides the necessary frameworks and classes to build graphical user interfaces and manage user interactions. Cocoa Touch incorporates various features, including touch-based event handling, standard controls (like buttons and sliders), and the overall application structure that conforms to Apple's Human Interface Guidelines.

This framework is essential for developers working on iOS applications, as it makes it easier to implement complex UI elements while maintaining the native look and feel of iOS applications. Additionally, Cocoa Touch also handles gestures and animations, which contribute to the overall user experience.

Other options represent different functionalities within the iOS architecture. Core Services deals with lower-level system services like data management and networking, Media focuses on the playback and processing of audio and video, while Core OS encompasses the operating system's kernel and fundamental components like security and file management. These layers play significant roles but do not specifically manage the user interface and graphics like Cocoa Touch does.
