Why is caution necessary while using phenol?

Answer and explanation

Correct answer: Because it is a hazardous chemical

The governing concept is laboratory chemical safety. Phenol can damage skin and eyes, is corrosive at relevant concentrations, and may be absorbed through the skin; its vapour and contact therefore require careful handling. In DNA extraction, phenol may help separate proteins from nucleic acids, but its usefulness does not make it harmless. Option A is correct. Option B is wrong because phenol is not a vitamin, and option C incorrectly treats a hazardous reagent as a nutrient. Option D is directly false because phenol is not water and is not harmless. Appropriate practice includes a fume hood where required, suitable gloves and eye protection, labelled containers, spill procedures, and disposal according to institutional safety rules.
