Answer:
Massively parallel processing
Explanation:
The modern-day supercomputing is done with quite a lot of microprocessors working together in parallel, simultaneously, and what we know as the Massively parallel processing. Nanocomputing is based on nanotechnology, and quantum computing is based on quantum mechanics, and cloud computing is a service and provides processors as infrastructure or IaaS. Hence, the correct option here is Massively parallel processing.
