W-12 is a virus that seriously damages the growth of grains, which causes a large amount of grain reduction every year. Scientists have found that inserting a gene extracted from W-12 into the genes of cereals that are susceptible to infection can make This cereal produces antibodies to W-12, thereby greatly reducing losses. All the following items, if true, can strengthen the above conclusions, except? ['Experience has shown that two grains are grown on the same land one after the other. If the first grain is not susceptible to a virus, the second grain is usually the same.', 'When plants obtain antibodies to a virus through genetic mutation, it will change some of their growth characteristics.', 'Plant-derived antibodies passed to offspring.', 'When plants obtain antibodies to one virus through genetic mutation, they will increase resistance to other viruses.']
