The correct answer is D. Software.
Software is the set of instructions that tells a computer what to do. It is the intangible part of a computer system that provides the user interface and controls the hardware. Software can be divided into two main categories: system software and application software.
System software is the software that controls the basic functions of a computer, such as the operating system, the file system, and the device drivers. Application software is the software that users interact with directly, such as word processors, spreadsheets, and games.
Hardware is the physical components of a computer system, such as the CPU, the memory, the storage devices, and the input/output devices. Hardware is the tangible part of a computer system that can be seen and touched.
Icons are small images that represent files, folders, or programs. They are used to make it easier for users to find and open the files and programs they need.
Information is data that has been processed in a way that makes it meaningful to humans. It can be stored in a variety of formats, such as text, numbers, images, and sounds.
None of these is the correct answer because they do not include the programs or instructions.
