Which of the following is an example of a logic circuit?

The microprocessor is an example of a logic circuit because it is fundamentally designed to perform logical operations and mathematical calculations using binary data. Logic circuits use simple operations like AND, OR, NOT, and combinations of these gates to perform more complex computations. The microprocessor contains numerous logic gates that enable it to execute instructions and manage data flow, making it the central component for processing information in computers.

In contrast, while a memory module is essential for storing data, it primarily serves as a storage unit rather than performing logical operations. A graphical processor is specialized for rendering images and graphics, focusing less on general logic processing. The control unit directs other components on how to execute instructions but is not a standalone logic circuit itself, instead working in conjunction with the microprocessor. Thus, the microprocessor is the clear choice for exemplifying a logic circuit in this context.
