Answer 1

The correct option is A A- T, B-S, C-P, D-R, E-Q

Sublimation- Iodine is a sublime substance. So, separation of iodine and sand can be done using this method.
Magnetic separation: Separation of iron and sand can be done using this method as iron has the magnetic properties.
Evaporation: Separation of dye from water can be done.
Solvent extraction: Separation of sand and wax can be done as wax is insoluble in solvent.
Fractional distillation: Separation of petroleum products can be done through this method.
