Which module of SPARC contains the general purpose registers?

The correct answer is: A. IU (Instruction Unit).

The IU (Instruction Unit) is the part of the SPARC processor that fetches and decodes instructions. It contains the general purpose registers, which are used to store data and intermediate results during the execution of instructions.

The FPU (Floating Point Unit) is responsible for performing floating point arithmetic. It does not contain any general purpose registers.

The CU (Control Unit) is responsible for controlling the execution of instructions. It does not contain any general purpose registers.

The control unit is a part of the CPU that is responsible for fetching instructions from memory, decoding them, and then executing them. It does not contain any general purpose registers.
