Which software type is specifically designed for use on mobile devices?

The correct choice is mobile applications because they are specifically designed to operate on mobile devices such as smartphones and tablets. These applications are developed to take advantage of the capabilities and features of mobile hardware, including touch screens, GPS, and camera functionalities. Mobile applications can be downloaded from app stores and are optimized for smaller screens and limited resources that are characteristic of mobile environments.

In contrast, application software is a broader category that includes any software designed to perform specific tasks for users, which may encompass desktop applications, web applications, and mobile applications. Utility software encompasses programs that help manage, maintain, and control computer resources, but is not limited to mobile environments. System software, including operating systems, provides the fundamental underlying infrastructure for hardware to function, but is distinct from applications designed specifically for mobile use.
