Answer

When chlorine gas is introduced to cold, dilute aqueous sodium hydroxide, a reaction occurs that primarily produces sodium chloride (NaCl) and sodium hypochlorite (NaClO). This reaction can be represented by the following equation:

Cl2+2NaOH→NaCl+NaClO+H2OCl_2 + 2NaOH \rightarrow NaCl + NaClO + H_2O

Thus, the correct answer is C) NaCl and NaClO.
