Which is the correct electron dot structure of $N_2O$ molecule?

The formal charges of $C$ and $O$ atoms in $CO_2$ $(\ddot{O}=C=\ddot{O})$ are,respectively:

For the ozone molecule,consider the following statements:
$(A)$ It is a linear molecule with a bond angle of $180^{\circ}$.
$(B)$ It is an angular molecule with a bond angle of $117^{\circ}$.
$(C)$ The bond lengths of both $O-O$ bonds are the same.
$(D)$ With respect to oxygen,it is thermodynamically more stable.
The correct options are:

The number of $3c-2e$ bond and $2c-2e$ bond present in $Be_2(CH_3)_4$ are $ . . . . . . $ and $ . . . . . . $ respectively.

The correct order of $C-O$ bond length among $CO, CO_3^{2-}, CO_2$ is
