Which of the following is NOT a way that a toxin can enter the body?

A toxin can enter the body through various routes, with ingestion, inhalation, and absorption being the primary pathways. Ingestion refers to the consumption of toxic substances through food or drink. Inhalation involves breathing in toxic fumes or particles, allowing them to enter the respiratory system and subsequently the bloodstream. Absorption describes the process where toxins penetrate the skin or mucous membranes and enter the body.

Reflection, on the other hand, does not pertain to a method of toxin entry. It is a term typically associated with light or other waves bouncing off a surface rather than a biological process for toxin exposure. Hence, reflection is not a viable route for toxins to enter the body, making it the correct answer to the question regarding methods of toxin entry.
