AS1 chemistry question

I’m really stuck on this ccea past paper question from 2017. If anyone has a second some help would be great ty.
Which of the following would exactly neautralise 10.0cm^3 of 1.00mol dm^-3 of NaOH(aq)?
A) 2.50cm^3 of 1.00 mol dm^3 CH3COOH
B) 5.00cm^3 of 1.00 mol dm^3 HCl
C) 5.00cm^3 of 1.00 mol dm^3 H2SO4
D) 3.00cm^3 of 1.00 mol dm^3 H3PO4

Hey there.
The NaOH would give 0.01 x 1 = 0.01 moles of OH-, which all needs to be neutralised. So you would need 0.01 moles of H+. Which acid would give 0.01 moles of H+?

Hi! do you multiply the concentration by the volume for each acid? and did u have to figure out if it was a 1:1 ratio of moles?
