Answer
A is false but R is true.
Explanation — The decomposition of vegetable matter (also called composting) is an exothermic reaction. Microbial activity breaks down the organic material and releases heat. Hence the assertion (A) is false.
A chemical reaction in which a compound splits into two or more simpler substances (elements or compounds) is called decomposition reaction. Hence the reason (R) is true.
