Which of the following is correct about the size pipelining registers in MIPS system?

1.) The pipelining registers are uniform in size and have the same size as the general purpose registers in the processor.

2.) The pipelining registers are uniform in size and are usually multiples of the size of the general purpose registers in the processor.

3.) The pipelining registers can be any sizes not uniformed and not multiples of the size of general purpose registers in the processor.

4.) The pipelining registers are not uniform in size but has to be multiples of the size of the general purpose register in the processor.
