Hi$,$I need help with this problem, please show and explain your solution clearly. I will upvote, thanks in advance!

Suppose you are trying to prove that L $=\{$ww $|$w in $\backslash$Sigma $\}$is not regular

using the pumping lemma. You have already assumed that L is regular, and let

p be the pumping length. Which of the following can you choose as the string s

which is pumped and leads to a contradiction? $($Circle all that apply.$)$

A$)0^$p$0^$p

B$)0^$p$1^$p

C$)(01)^$p

D$)0^($p$1)10^($p$1)1$

$(2$ points$)$ Suppose you are trying to prove that $L=\{ww|win{}^{*}\}$ is not regular

using the pumping lemma. You have already assumed that $L$ is regular, and let

$p$ be the pumping length. Which of the following can you choose as the string $s$

which is pumped and leads to a contradiction? $($Circle all that apply.$)$

$0^p{0}^p$

$0^p{1}^p$

$(01{)}^p$

$0^{p-1}{10}^{p-1}1$
