So the way I'd solve this problem would be to go through each answer and ask myself why it is true/not true. For A, it is true that engineers try to breed disease from their plants. And from just a common sense point of view, wouldn't you want to rid your plants of disease? For B, it doesn't make sense to get rid of watering entirely. That's one of the fundamental things of a plant, besides sunlight and CO2. For C, you can't control the weather, and pests can be stopped using pesticides, which are cheaper than breeding a new plant type. For D, it doesn't make sense to want your plants to grow better from herbicides. So, my answer would be A as it is the best fitting option
