Corrosive is defined as a chemical that causes destruction or necrosis of living tissue at the site of contact.

• A. Corrosive
• B. Exposure Routes
• C. Flammable Liquid
• D. Health Hazard

Answer: (A)

Corrosive is the term that fits because the definition describes a chemical that damages or destroys living tissue on contact. That tissue-destroying action at the contact site is the defining feature of a corrosive substance, which can cause chemical burns and necrosis. This is different from exposure routes, which talk about how a chemical can enter the body (ingestion, inhalation, dermal contact) rather than what damage it can cause. Flammable liquid describes a hazard related to ignition and burning, not tissue destruction. Health hazard is a broad category that covers many adverse effects but doesn’t specify the tissue-destroying action at contact. So corrosive best matches the description.
