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:

{$E\, =$ Central atom, $B\, =$ Terminal atom, $L\, =$ Lone pair}
