Which term refers to a chemical substance used to kill harmful insects, small animals, wild plants, and other unwanted organisms?

• A. Fertiliser
• B. Pesticide
• C. Flood
• D. Sustain

Answer: (B)

A pesticide is any chemical substance used to kill or control harmful organisms, including insects, rodents, weeds, and fungi. This term covers a range of products such as insecticides, herbicides, rodenticides, and fungicides, and they’re commonly used in agriculture, gardening, and public health to protect crops and reduce pest problems. Fertiliser, by contrast, feeds plants by supplying nutrients; floods describe an overflowing amount of water; sustain means to maintain or support something. None of those describe a chemical meant to kill unwanted organisms, so the term that fits is pesticide.
