Restricted-entry intervals (REIs) refer to the amount of time that must pass before workers are allowed to enter an area that has been treated with pesticides. This interval is important to ensure the safety of workers and reduce the risks of exposure to harmful chemicals. Options A, B, and D are incorrect because they do not pertain to the interval between application and reentry. Option A refers to proper storage of the pesticide, option B refers to the drying time for the pesticide, and option D refers to mixing instructions. These are all important factors to consider, but they do not directly relate to the restriction of worker reentry. Option C is the correct answer as it specifically addresses the time interval for worker safety.
