(iv) neutralisation reaction
(a) (i) and (iv)
(b) (ii) and (iii)
(c) (i) and (iii)
(d) (iii) and (iv)

Solution: Answer is (c)  (i) and (iii)

The reaction described here is a combination of displacement and redox reactions. The displacement reaction occurs when oxygen displaces hydrogen in ammonia, resulting in a displacement reaction. A redox reaction occurs when nitrogen is oxidised and oxygen is reduced, resulting in the reduction of nitrogen and the reduction of oxygen.
