hey kavya ,

 the correct answer for this question is  

d) 2-methylpropane-2-ol...because  

Time taken for turbidity to appear is a measure of the reactivity of the class of alcohol with Lucas reagent, and this is used to differentiate between the three classes of alcohols:no visible reaction: primary, such as normal amyl alcohol (1-Pentanol)solution turns cloudy in 3-5 minutes: secondary, such as sec-amyl alcohol (2-Pentanol)solution turns cloudy immediately, and/or phases separate: tertiary, such as tert-amyl alcohol (2-Methyl-2-butanol).
