The correct answer is: $\mathrm{BF}_3$ does not have dipole moment
(1) For $\mathrm{NH}_4^{+} ; \mathrm{No}$. of $\mathrm{V} \cdot \mathrm{E}=10$
For $\mathrm{CH}_4$; No. of $\mathrm{V} \cdot \mathrm{E}=10$
They are isoelectronic species.
(2)

(3)$\mathrm{O}-\mathrm{Cl}-\mathrm{O}$ does not follow octet rule.
(4)
