(C) Given: Initial $pH = 3$. Since $pH = -\log[H^{+}]$,we have $[H^{+}]_1 = 10^{-pH} = 1 \times 10^{-3} \ M$. Using the dilution formula $M_1 V_1 = M_2 V_2$: $(1 \times 10^{-3} \ M) \times (20 \ mL) = M_2 \times (100 \ mL)$. $M_2 = \frac{1 \times 10^{-3} \times 20}{100} = 2 \times 10^{-4} \ M$. Therefore,the final $H^{+}$ ion concentration is $2 \times 10^{-4} \ M$.
