While genetic modification of food has numerous advantages, some people are concerned about the potential of genetically modified crops to a.) add vitamin and mineral supplements to food. b.) target harmless insects unintentionally. c.) clean up pollution in contaminated soil. d.) resist extreme temperature changes.

The best answer to the question: While genetic modification of food has numerous advantages, some people are concerned about the potential of genetically modified crops to:___, would be, B) Target harmless insects unintentionally.

Explanation:

Although it is undeniable that genetically modified crops have become an advantage because they are resistant to insects, and therefore may require the use of less pesticides, it has also become a threat for the survival of species that are not harmful either to crops, or to human health, and whose existence may be dependent on those who are. Thus, genetically modified food from crops may put an ecosystem´s balance at risk by targeting insects that cause damage to crops, but, are essential for the survival of other species.
