Explanation: The by-product of a chemical reaction that is generated in the highest quantity. will result in the ions and acid being in equilibrium.
The nitric acid may get heated enough to dissolve themHNO3 in water andNO2 sufficient sulfuric acid is added (gas). not a reaction between the two, but has to do with heat.

Explanation for the incorrect options:
(a)
Explanation: The by-product of a chemical reaction that is generated in the highest quantity.
In figure1, the −ve charge is carried byNO2.It is less stable.
Diagram:
(b)
Explanation: In figure2, OH is more electronegative. −ve charge on a more electronegative atom makes it more stable. It is most stable.
Diagram:
(d)
Explanation: The by-product of a chemical reaction that is generated in the highest quantity.
In figure 4, CH3resonance is taking place. It is more stable.
