Which one of the following compounds gives a positive iodoform test?

Prof. Sandy Gilbert asked his students to prepare $2$-chloropropane by different methods:
Kaushal's method: $CH_3-CH(OH)-CH_3 \xrightarrow{KCl}$
Preeti's method: $CH_3-CH=CH_2 \xrightarrow{Cl_2 + H_2O}$
Raghav's method: $CH_3-CH(OH)-CH_3 \xrightarrow[Pyridine]{SOCl_2}$
