A
Both (1) and (2)
💡 Explanation:

Statement (1) is correct. Froth flotation is one of the processes used to recycled paper. In the paper industry this step is called deinking or just flotation. The target is to release and remove the hydrophobic contaminants from the recycled paper. The contaminants are mostly printing ink and stickies.
Statement (2) is correct. Distillation is the process of heating a liquid to its boiling point, capturing and cooling. Extraction of petroleum, diesel, naphthalene and bitumen is the example of fractional distillation.
