answer $($c$)$

$($c$)(6$marks$)$If you consider the circuit synchronous, draw the circuit of its $2-$bit asynchronous counterpart using D flip$-$flops. If you consider the circuit asynchronous, draw the circuit of its $2-$bit synchronous counterpart using D flip$-$flops. Your circuit should have the Enable function, where the outputs would not change when Enable is logic $0.$The D flip$-$flops used should have Set and Reset connections like those in the circuit on the right, which should be connected properly.
