Select correct statement about hydrolysis of ${\mathrm{BCl}}_3$and ${\mathrm{NCl}}_3$ .

${\mathrm{NCl}}_3$is hydrolysed and gives $\mathrm{HOCl}$ but ${\mathrm{BCl}}_3$is not hydrolysed.

Both ${\mathrm{NCl}}_3$ and ${\mathrm{BCl}}_3$ on hydrolysis gives $\mathrm{HCL}$.

Both ${\mathrm{NCl}}_3$ and ${\mathrm{BCl}}_3$ on hydrolysis gives $\mathrm{HOCl}$.

${\mathrm{NCl}}_3$ on hydrolysis gives $\mathrm{HOCl}$ but ${\mathrm{BCl}}_3$ gives $\mathrm{HCL}$.
