Solution

The correct options are
A

C+4HNO3CO2+2H2O+4NO2


C

S+6HNO3H2SO4+2H2O+6NO2


D

3Zn+8HNO33Zn(NO3)2+4H2O+2NO


Nitric acid is a strong oxidizing agent whereby it undergoes reduction in a number of ways. Hence, it can get reduced to NO, NO2 N2O etc.

3Zn+8HNO33Zn(NO3)2+4H2O+2NO

In the above reaction, nitric acid gets reduced to NO. From the given options, only the following reaction is where nitric acid behaves as an acid and not as an oxidizing agent.

K2O+2HNO32KNO3+H2O

So it looks like nitric acid behaves as an acid with bases or basic oxides. On the other hand, it tends to behave as an oxidizing agent when HNO3 reacts with elements - metal or non-metal!
