For the circuit in the below drawing and value of parameters:

$t_h=2ns$

$T=clk$ period $=15ns$

$T_{\text{d}\text{e}\text{k}\text{A}}=10ns$

$t_{co}=3ns$

$T_{\text{d}\text{a}\text{t}\text{a}}=15ns$

$T_{\text{d}\text{u}\text{k}\text{B}}=20ns$

$t_{su}=3ns$

$1)$what is the setup required time in ns$?$

$32$ns

$35$ns$,15$ns

$13$ns

$2)$ is the design safe $?$

Yes

No

Insufficient info

Either yes or no depending on other parameters
