The following reaction is an example of a
`4NH_(3)(g)+5O_(2)(g)rarr4NO(g)+6H_(2)O(g)`
1. displacement reaction
2.combination reaction
3. redox reaction
4.neutralisation reaction

Options

A. (i) and (iv)
B. (ii) and (iii)
C. (i) and (iii)
D. (iii) and (iv)

Answer

B

Explanation

The given reaction is a redox reaction because oxidation and reduction both take place simultaneously. Also, it is a displacement reaction because hydrogen of `NH_(3)` has been displaced by oxygen.
