Which of the following substances is isoelectronic with ${N_2}O$ and has a similar structure?

Consider the following statements:
$A$. $NF_3$ molecule has a trigonal planar structure.
$B$. Bond length of $N_2$ is shorter than $O_2$.
$C$. Isoelectronic molecules or ions have identical bond order.
$D$. Dipole moment of $H_2S$ is higher than that of water molecule.
Choose the correct answer from the options below:

In the $OF_2$ molecule,the number of bonding and lone pairs of electrons are,respectively,........

The number of molecules from the following which contain only two lone pairs of electrons is $........$.
$H_2O, N_2, CO, XeF_4, NH_3, NO, CO_2, F_2$

Amongst the following,the total number of species $NOT$ having $8$ electrons around the central atom in its outermost shell is $NH_3$,$AlCl_3$,$BeCl_2$,$CCl_4$,$PCl_5$:
