Answer
Both A and R are true and R is the correct explanation of A.
Explanation — An equation must be balanced in order to comply with the "Law of Conservation of Matter", which states that matter is neither created nor destroyed in the course of a chemical reaction. Hence, the assertion (A) is true.
An unbalanced equation would imply that atoms have been created or destroyed. Hence, both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
