Which one of the following correctly shows the neutralization equation between a diprotic acid and sodium hydroxide?

$H_{2}A(aq)+2$NaOH$(aq)N{a}_{2}A(aq)+2H_{2}O(l)$

$H_{2}A(aq)+$NaOH$(aq)$NaA$(aq)+H_{2}O(I)$

$H_{2}A(aq)+2$NaOH$(aq)H_{2}Na(aq)+2A_{2}OH(aq)$

$HA(aq)+2$NaOH$(aq)$NaA$(aq)+2H_{2}O(l)$

$2HA(aq)+$NaOH$(aq)$HNa$(aq)+2$AOH$(aq)$
