NaOH(aq) + HCl(aq) → NaCl(aq) + H2O(l)

Reason: a neutralization reaction is an acid + base producing a salt and water. The NaOH (base) + HCl (acid) fits this. The Pb and Ag reactions are precipitation/double-displacement; Fe2O3 + HCl is acid + metal oxide (can be called neutralization in a broader sense), but the clear textbook neutralization is the NaOH + HCl reaction.
