Which of the following is the monomer of $Nylon-6$?

The $trans$-form of polyisoprene is:

Which among the following formulae represents the $\omega$-amino caproic acid?

Given below are two statements:
Statement $I:$ Ethene at $333$ to $343 \ K$ and $6-7 \ atm$ pressure in the presence of $AlEt_3$ and $TiCl_4$ undergoes addition polymerization to give $LDP$.
Statement $II:$ Caprolactam at $533-543 \ K$ in $H_2O$ through step growth polymerizes to give Nylon-$6$.
In the light of the above Statements,choose the correct answer from the options given below:

The repeating unit of $PCTFE$ is .........

Match List-$I$ with List-$II$.
