Final answer:
To reduce honey bee mortality caused by pesticides, it is recommended to remove bee hives from sprayed crops, use non-hazardous pesticides, and avoid spraying on blooming plants. Therefore, the correct option is D.
Step-by-step explanation:
It takes a comprehensive strategy to lower pesticide-related honey bee mortality. Option A, removing bee hives from pesticide-sprayed locations, can shield bee colonies from direct exposure. Making arrangements with farmers to apply non-toxic pesticides to bees (option b) is a proactive step to reduce the damage to pollinators.
Since bees are more likely to graze on flowering plants and exposure during this period might be particularly damaging, it is imperative that spraying be avoided on blooming plants (option c). Putting all three of these alternatives (a, b, and c) into practise at once offers a more effective way to protect honey bee populations from the harmful effects of pesticides.
Therefore, the correct option is D.
