B. Red, blue, colourless

Step-by-step solution

Victor Meyer's test: The various steps involved are (i)RCH2OH→HIRCH2\mathrm{RCH}_2 \mathrm{OH} \xrightarrow{\mathrm{HI}} \mathrm{RCH}_2\mathrm{I}→AgNO2RCH2NO2\xrightarrow{\mathrm{AgNO}_2} \mathrm{RCH}_2 \mathrm{NO}_2 In the Victor-Meyer's test, the colour given by 1^ ^ .2^ ^ and 3^ ^ alcohols are respectively: (ii)In the Victor-Meyer's test, the colour given by 1^ ^ .2^ ^ and 3^ ^ alcohols are respectively:
In the Victor-Meyer's test, the colour given by 1^ ^ .2^ ^ and 3^ ^ alcohols are respectively: (iii) R3COH→HIR3CI→AgNO2R3CNO2−→HNO2\mathrm{R}_3 \mathrm{COH} \xrightarrow{\mathrm{HI}} \mathrm{R}_3 \mathrm{CI} \xrightarrow{\mathrm{AgNO}_2} \mathrm{R}_3 \mathrm{CNO}_2-\xrightarrow{\mathrm{HNO}_2} No reaction →KOH\xrightarrow{\mathrm{KOH}} Colourless
