The following are some statements about oxides
of VA group elements
I) N₂O molecule is linear
II) NO₂ molecule is angular
III) N₂O₅ molecule is angular
The correct combination is

N₂O is a polar molecule that has a linear shape.

There are lone pairs on both O and N atoms in NO₂. As a result, the oxygen atoms are spread widely and the angle that is formed is nearly134^o. This implies that NO₂ molecular geometry will be bent.

Solid N₂O₅ is a salt, consisting of separated anions and cations. The cation is the linear nitronium ion, ${\mathrm{NO}}_2^{+}$ and the anion is the planar nitrate ion, ${\mathrm{NO}}_3^{-}$.
