$(3)$ Compare the $16,32$ and $64$ register Simple RISC for OPCode at bit$31..$bit$26($Option $1)$ and OPCode at bit$5..$bit$0($Option $2).$

$-(3\mathrm{.}1)$ For how many bits are available for the Integer$-$Immediate fields for $16,32$ and $64$ registers?

$-(3\mathrm{.}2)$ For how many bits are available for the Jump class instructions offset fields for $16,32,$ and $64$ registers

Option $1$

NOTE: Instruction word size is $\backslash (\backslash$mathbf$\{32\}\backslash )$ bits for all project $\backslash (\backslash$mathbf$\{1\}\backslash )$ cases
