The correct option is D NO+2
The ONO angle is maximum in NO+2
In NO−3, bond angle is =120∘ due to sp2 hybridization with no lone pair NO+2,NO−2 and NO2 have bond angles nearly nearly 180∘(sp) with one lone pair, 115∘(sp2) with one lone pair and 134∘ respectively.
Thus, ONO angle is maximum in NO+2.
