The answer is (B).

$n\text{(NaOH) reacting}\:=0.10\times 10.0\times 10^{-3}=1.0\times 10^{-3}\:\text{mol}$

This requires $1.0\times 10^{-3}$ mol HCl or $1.0\times 10^{-3}$ mol $CH_3COOH$ for complete reaction.

There is $0.10\times 10.0\times 10^{-3}=1.0\times 10^{-3}$ mol of both acids present, so both solutions will react completely with the NaOH.

I hope this helps!
