Given below are two statements:

Statement $(I)$ : Both metal and non-metal exist in $\mathrm{p}$ and $d$-block elements.

Statement $(II)$ : Non-metals have higher ionisation enthalpy and higher electronegativity than the metals.

In the light of the above statements, choose the most appropriate answer from the option given below:

An organic compound '$A$' contains nitrogen and chlorine. It dissolves readily in water to give a solution that turns litmus red. Titration of compound '$A$' with standard base indicates that the molecular weight of ' $A$ ' is $131\,\pm\,2$. When a sample of '$A$' is treated with aq. $NaOH$, a liquid separates which contains $N$ but not $Cl$. Treatment of the obtained liquid with nitrous acid followed by phenol gives orange precipitate. The compound '$A$' is.
