The total H+ ions in the final solution will be :
 
mol of H2SO4 in 20 ml of 1M solution = (20 X 1) / 1000 = 0.02 mol H2SO4
 
mol of HCl in 10 ml of 1M solution = (10 X 1)/1000 = 0.01 mol HCl
 
Total volume of acid = 10 + 20 = 30
 
Total moles of acid (H+) = 0.02+0.01 = 0.03 mol H+
 
Total 0.03mol H+ dissolve in 30ml of solution and
 
 
Mol of NaOH in 30 ml of 1M solution = (30X1)/1000 =0.03 mol
 
on mixing both acid and base we get = 0.03-0.03 = 0
 
Hence option C will be the correct answer.
