Which of the following statements is true regarding organophosphate insecticides?

Organophosphate insecticides are indeed commonly used for agricultural purposes, making the statement accurate. These chemicals are widely utilized in farming to control a variety of pests that can damage crops. Their effectiveness in breaking down the nervous system of insects makes them a go-to choice for farmers looking to protect their produce.

The other statements do not hold true in this context. For instance, organophosphates are known for their potential toxicity to humans and other non-target organisms, contradicting any claims about low toxicity. While some insecticides may repel pests, organophosphates are primarily lethal to them rather than just deterring their presence. Additionally, they are not exclusively used indoors; their applications are expansive and can occur both indoors and outdoors, particularly in agricultural settings.
