Step 1
C Fractions are separated based on their boiling point.
Answer
Fractional distillation is a technique used to separate components of a mixture based on differences in boiling points. In this process, the mixture is heated, and as the temperature rises, different fractions vaporize at their respective boiling points. The vapor is then cooled and condensed back into liquid, allowing for the collection of separated fractions. Therefore, the correct statement about fractional distillation is option C.
