As we have learnt,

Alcohols can be converted to alkenes by passing their vapours overheated alumina (Al_2O_3). More the surface area of Al_2O_3, more will be the efficiency of the reaction.

CH_3-CH(OH)-CH_3\xrightarrow[450^{\circ}]{Al_2O_3}CH_3-CH= CH_2+H_2O

Hence, the correct answer is Option (4)
