(B) The sequence of reactions described is the $Victor \ Meyer's \ test$,used to distinguish between primary,secondary,and tertiary alcohols. $1.$ Primary alcohols $(1^\circ)$ give a blood-red color. $2.$ Secondary alcohols $(2^\circ)$ give a blue color. $3.$ Tertiary alcohols $(3^\circ)$ give no color (remain colorless). Among the given options,$CH_3-CH(OH)-CH_2-CH_3$ (Butan-$2$-ol) is a secondary alcohol,therefore it produces a blue color.
