Which of the following systems require multiple register sets:
a) a scalar processor,
b) a superscalar processor
c) a multi-core system
d) hyper-threaded (i. e. simultaneous multi-threading) system.
list your answers as a), b) c), etc. more than one choice may apply.

C) Multi-core system

Explanation:

 Multi core system is the computer processor that basically require two and more than two individual processing system which are integrated into the system. Each processing units are known as core and it basically execute and read the instruction of the program in the multi-processor computer.

On the other hand, in the scalar processor it does not require any  multiple register set as the central processing unit (CPU) perform various computations in the data. It execute only single instruction.

The super class processor execute many instruction in the clock cycle in the single system processor.

And the hyper multi threading processor acts as a multiple processor in the system and it basically allow multiple threading in the system.

Therefore, Option (C) is correct.
