Answer

Brief Explanations:

The sodium - hydroxide solution spilled on his arm. Absorption is the process by which a substance passes through the skin into the body. Since the chemical came into contact with the skin and caused a reaction, the route of entry is absorption. Inhalation involves breathing in a substance, ingestion is taking it in by mouth, and injection is introducing it into the body by a needle - like device. None of these apply here.

Answer:

D. Absorption
