The answer is Ingested corrosives may be diluted by drinking 4–6 oz (113.4–170.1 ml) of water or milk. If vomiting is persistent, do no attempt to administer additional fluids. Avoid neutralization therapies as the resultant exothermic reaction may cause additional tissue injury.
Explanation :
- Strong acids, corrosive agents, and highly reactive oxidants can cause large-scale destruction of living cells through direct chemical reactions. Sometimes referred to as necrotic cell death, this non-specific effect is induced by concentrated solutions of caustic and caustic chemicals that cause indiscriminate cell destruction.
- A generalized overwhelming effect of this type is no different from those resulting from "burning" tissue. These chemically induced injuries are commonly referred to as "chemical burns."
- Such effects are produced not only by strong acids or bases in harmful concentrations, but also by exposure to concentrated solutions of organic solvents such as ether, chloroform or carbon tetrachloride. The intensity of such non-specific toxicity is directly related to the concentrations of the chemical agents when in contact with the target tissues.
- Widespread cell destruction can be caused by any chemical that is sufficiently soluble in tissue fluids to access cells at high concentrations. The effects of these chemicals in higher organisms are generally limited to easily accessible tissues such as the skin, eyes, mouth, nasal mucosa, and respiratory tract.

Answer: b. DNA
Explanation:
DNA is a genetic material commonly found in all living beings. It is present in a thread like structure that is called as the chromosome. The DNA is double helical structure which exhibits the segments of small units called as the genes. The gene is a hereditary material which encodes for a particular protein. Each gene is responsible for determining a particular trait in living beings.
