Which of the following compounds gives the dye test?

Identify the reagent used to distinguish primary and secondary amines by the $Hinsberg$ test.

Given below are two statements:
Statement $I$: All the following compounds react with $p$-toluenesulfonyl chloride:
$C_6H_5NH_2$
$(C_6H_5)_2NH$
$(C_6H_5)_3N$
Statement $II$: Their products in the above reaction are soluble in aqueous $NaOH$.
In the light of the above statements,choose the correct answer from the options given below.

Match List-$I$ with List-$II$:
