In (cii) it says hcl (aq) which means there should be H2O molecules too along with hcl molecules in the reagent i.e it's diluted.

Why can't H2O replace NH2 in a nucleophilic substitution reaction and OH bonded instead of NH2 in the new structure?Name:  Screenshot_20200227-045013__01.jpg

Water, H2O isn't very good at displacing things by substitution. If it was deprotonated as -OH, then it might have a chance (though still not very strong because NH2 isn't very good at being removed).
In this case, because you have an acid, the substitution step will not take place.
