and the following table:

Unit

Delay $($ns$)$

PC

$0\mathrm{.}66$

Instruction Memory

$1\mathrm{.}93$

Muxes

$0\mathrm{.}34$

Control Units

$0\mathrm{.}70$

Register File $($read or write$)$

$1\mathrm{.}33$

ALU

$3\mathrm{.}58$

Data Memory

$2\mathrm{.}10$

Adder

$0\mathrm{.}87$

If the instruction includes only the instructions lw$,$ sw$,$ beq and R$-$type instrucitons, choose the correct value for the clock cycle in ns$.$
