To balance a chemical reaction it is important to remember that the atoms of each element in the reactant and the product side should be the same or equal in number. Therefore, the correct answer is the first option. The balanced equation is:

2NaOH + H2 SO4 -----> Na2SO4 + H2O

Hope this answers the question. Have a nice day. 

The answer is C 2,1,1,2
