Solution

The correct option is A True
$H N O_{2}$ (Nitrous acid) is monobasic acid because it can donate only a single proton.
Basicity is the number of protons that an acid can give. From the structure,

We can see that there is only one H atom and so only one proton can be abstracted from a $H N O_{2}$ molecule. What can you say about the basicity of nitric acid?
