• C. The environmental persistence of the pesticide.
• D. The price of the pesticide.

Answer: (A)

Pesticide toxicity is the potential for a pesticide to cause harm to a living organism. It describes how harmful the chemical can be if an exposure occurs, taking into account factors like the amount encountered, how the exposure happens (ingesting, inhaling, or skin contact), and how long the organism is exposed. A substance with high toxicity can cause serious or immediate damage even at low doses, while a less toxic product needs much higher exposure to cause harm. This concept is about biological harm, not how the product looks on the label, how long it stays in the environment, or what it costs. In safety and regulatory practice, understanding toxicity helps determine safe handling, protective equipment, application methods, and precautions to protect workers, bystanders, and non-target organisms.
