Question 719 Deck General

The correct answer is B) Oleum. Oleum, also known as fuming sulfuric acid, is the most irritating to the skin among the given options. Oleum is an extremely corrosive and hazardous substance that can cause severe skin burns and tissue damage upon contact. The other options, such as ethyl alcohol, isoprene, and carbon disulfide, while potentially harmful, are generally less irritating and corrosive to the skin compared to the highly reactive and acidic nature of oleum.
