Explanation:

The correct option is (C) Hardware. Hardware refers to the physical components of a computer system that you can touch and see. This includes the central processing unit (CPU), memory (RAM), storage devices (hard drives, SSDs), input devices (keyboard, mouse), output devices (monitor, printer), and all other tangible electronic components that make up the computer. (A) Operating system is a type of software that manages computer hardware and software resources. It is not a physical component. (B) Software refers to the set of instructions, data, or programs used to operate computers and execute specific tasks. It is intangible. (D) Web browsers are a specific type of application software used to access information on the World Wide Web. They are not physical components. (E) None of these is incorrect because 'hardware' is the precise term for the physical components.
