Which of the following statements is true regarding pesticide storage?

Pesticides must be stored in cool, dry places to maintain their effectiveness and prolong shelf life. Heat and moisture can deteriorate the chemicals, leading to reduced efficacy and potential safety hazards. Storing liquids on the bottom shelf is also important for safety reasons, as it prevents spills from contaminating other products, reducing the risk of accidents or exposure to harmful substances. This practice helps ensure that the pesticides remain stable and safe to use while preventing any cross-contamination with other stored materials.

The other options suggest conditions that would compromise pesticide integrity or safety, such as warm and moist environments, or exposure to direct sunlight, which are not suitable for proper pesticide storage.
