As we have learnt,

Chlorine reacts with NaOH and Ca(OH)_2 and undergoes disproportionation. The products depend upon the concentration of the base and also the temperature.

The reactions are given as 

2Na(OH) + 3 Cl_2 \longrightarrow NaClO_3 +5 NaCl + 3 H_2O

(Hot and Conc.)

2 Ca(OH)_2 + 2 Cl_2 \longrightarrow Ca(OCl)_2 + CaCl_2 + 2 H_2O

 (Dry)

Therefore, Option(4) is correct.
