An aqueous solution of HN₃ was diluted two times, three times, four times and five times using required amount of water. Considering ‘α’ to be the ionization constant and ‘V’ as the final volume of diluted solution, choose the correct answer from the following:

1. (a) All the solutions will be acidic and the graph of α vs. V is non-linear
2. (b) All the solutions will be basic and the graph of α vs. V is non-linear
3. (c) All the solutions will be acidic and the graph of α vs. V is linear
4. (d) All the solutions will be basic and the graph of α vs. V is linear
