Solution

The correct option is C Assertion is correct but Reason is incorrect
$C H_{4} + 2 O_{2} \to C O_{2} + 2 H_{2} O,$ is combustion process so its an exothermic process.
Respiration is an exothermic process because it releases large amounts of energy to the surroundings.
During respiration, glucose molecules are converted to other molecules in a series of steps. They finally end up as carbon dioxide and water.
The overall reaction is
$C H O + 6 O 6 C O + 6 H O + 2805 k J$
