Solution
The correct option is C glass
The fractionating column with glass beads is fitted in the neck of the distillation flask containing the mixture of liquids to be separated.
The glass beads present in the fractionating column provide a large surface area for hot vapours to cool and condense repeatedly.
Glass is used because it is chemically very stable. It reacts with very few substances and thus, the composition of mixture remains intact.
