Match the following Column-I and Column-II and choose the correct option: Column-I Column-II (a) Exothermic reaction (i) Removal of 'O' atom (b) Oxidation reaction (ii) Energy absorbed (c) Endothermic reaction (iii) Addition of 'O' atom (d) Reduction reaction (iv) Energy released

(a)-(iv), (b)-(iii), (c)-(ii), (d)-(i) (a)-(i), (b)-(iii), (c)-(ii), (d)-(iv) (a)-(iv), (b)-(ii), (c)-(iii), (d)-(i) (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i)

(a)-(iv), (b)-(iii), (c)-(ii), (d)-(i)

The correct answer is option 1. (a)-(iv), (b)-(iii), (c)-(ii), (d)-(i) Column-I Column-II (a) Exothermic reaction (iv) Energy released (b) Oxidation reaction (iii) Addition of 'O' atom (c) Endothermic reaction (ii) Energy absorbed (d) Reduction reaction (i) Removal of 'O' atom
