(A) an oxidation and an exothermic reaction.
(B) a reduction and an endothermic reaction.

• A. Only A is true
• B. Only B is true
• C. Both A and B are true
• D. Both A and B are false

Answer 1

The correct option is A Only A is true

In the process of combustion

$C+O_2\to C{O}_2$

oxidation state of carbon is increased and addition of oxygen takes place that means oxidation of carbon is taking place,

during the combustion, bond formation takes place and energy is released, that means it is an exothermic reaction.
