Which of the following devices is an example of a PC?

The most suitable choice as an example of a PC (Personal Computer) is a laptop computer. A laptop is designed primarily for individual use and features the capabilities of a traditional desktop computer, allowing users to perform various tasks such as word processing, running applications, and accessing the internet.

Laptops have a full operating system and usually come with a keyboard, trackpad, and larger screen, making them versatile for work and personal use. They are portable, enabling users to carry them easily, which aligns with the essence of a personal computing device.

In contrast, while smartphones and tablets are indeed personal devices, they represent a different category as they often run on mobile operating systems, prioritize touch interfaces, and may not support the full range of applications and user experiences that traditional PCs offer. Smartwatches, on the other hand, are designed specifically for wearable convenience and do not function like conventional PCs, focusing instead on notifications, fitness tracking, and limited app usage.
