What can be concluded about a pesticide label without a signal word?

In the context of pesticide labels, the absence of a signal word does not provide definitive information regarding the safety or toxicity of the product. The primary purpose of signal words—such as "Caution," "Warning," and "Danger"—is to convey the level of acute toxicity associated with the pesticide. However, a label without a signal word does not imply that the product is non-toxic or safe; it may simply mean that the product does not meet the specific criteria for signal word classification set by regulatory bodies. Therefore, without additional context or information, no particular conclusion about the toxicity or safety of the pesticide can be accurately drawn, leading to the conclusion that none of the provided options are correct.
