Polymers

Given below are two statements : Statement I : Ethene at 333 to $343 \mathrm{~K}$ and $6$-$7$ atm pressure in the presence of $\mathrm{AlEt}_{3}$ and $\mathrm{TiCl}_{4}$ undergoes addition polymerization to give LDP. Statement II : Caprolactam at $533$-$543 \mathrm{~K}$ in $\mathrm{H}_{2} \mathrm{O}$ through step growth polymerizes to give Nylon 6. In the light of the above statements, choose the correct answer from the options given below:
