What type of processor has multiple CPUs on a single chip?

A multi-core processor is designed with multiple CPUs integrated onto a single chip. This allows for parallel processing, enhancing the CPU's ability to handle multiple tasks simultaneously, which improves performance for multi-threaded applications and overall system efficiency.

The concept of a multi-core processor encompasses a range of configurations, meaning it can include two or more cores, such as in dual-core or quad-core processors. This makes the multi-core architecture versatile and scalable, accommodating various computational needs by adding more cores as required.

In contrast, options like single-core indicate only one CPU on a chip, while dual-core and quad-core specify the number of cores but do not encapsulate the broader category of processors that could have more than four cores. Thus, the term "multi-core" accurately reflects the general nature of processors with more than one core integrated, which is why it is the correct choice.
