There are three substances in the equation, so we need three coefficients.
Let's start with NaOH:
2 NaOH   
Next, we'll add H2SO4:
2 NaOH + H2SO4 
Now, we need to balance the equation by adding coefficients to H2O:
2 NaOH + H2SO4 → Na2SO4 + 2 H2O
As a result, we need the coefficients to be 2, 1, and 2, which corresponds to choice C.
