Answer

The correct answer is **c. Potentiation**.Here's why:* **Potentiation** occurs when a non-toxic substance increases the toxicity of another substance. The non-toxic substance itself doesn't cause a toxic effect, but it enhances the toxicity of the other substance.Let's look at the other options:* **Additive effect:** The combined effect of two substances is equal to the sum of their individual effects. (1 + 1 = 2)* **Synergistic effect:** The combined effect of two substances is greater than the sum of their individual effects. (1 + 1 = 3)* **Antagonistic effect:** One substance reduces or blocks the effect of another substance.Therefore, potentiation is the specific term for one substance increasing the toxicity of another.
