1. Fractional distillation. As they are miscible. Pls mark me brainliest

1) The method which is used to separate a mixture of oil and vinegar is separation by density. Density is defined as the ratio of mass to the amount of matter i.e. volume
2) Hand sorting was the first method used in the history of waste sorting. Waste can also be sorted in a civic amenity site. "Waste segregation" means dividing waste into dry and wet. Dry waste includes wood and related products, metals and glass.
3) The distillation of sugar solution results in pure sugar. Therefore, we can separate the sugar by the process of distillation to obtain pure crystals. Hence, (A) is the correct option. Note: The sugar can be separated using a process called evaporation.

The answer is option a.
