Answer :
Just to help to understand what is happening here, I will show you the complete non ionic reaction (this is just a reference not the answer)
NaOH (aq) + HCl (aq) -> NaCl (aq) + H2O
Now, you have to separate the ionics substances into the ions, which gives the desired answer:
Na+(aq)+OH−(aq)+H+(aq)+Cl−(aq)→ Na+ (aq) + Cl- (aq) + H+ (aq) + OH- (aq)
NaOH (aq) + HCl (aq) -> NaCl (aq) + H2O
Now, you have to separate the ionics substances into the ions, which gives the desired answer:
Na+(aq)+OH−(aq)+H+(aq)+Cl−(aq)→ Na+ (aq) + Cl- (aq) + H+ (aq) + OH- (aq)
