The correct option is A True
The given statement "A balanced equation contains equal number of atoms of each element on both sides of the equation." is true. For example, consider the combustion of C.
C+O2→CO2
On LHS, the number of C atoms is 1.
On RHS, the number of C atoms is 1.
Thus, the number of C atoms on LHS is equal to the number of C atoms on RHS.
On LHS, the number of O atoms is 2.
On RHS, the number of O atoms is 2.
Thus, the number of O atoms on LHS is equal to the number of O atoms on RHS.
