Which of the following is the basis for one concern regarding the broad planting of BT-toxic crops? BT-modified crops may kill pollinators, reducing crop fertility in seed and fruit crops

pollinating species will come to prefer BT-modified crops, and will leave non-GMO crops unfertilized

species of beneficial pollinators will develop a natural immunity to the BT toxins

exposure to BT may turn insects into super insects, resulting in things like BT-toxic bee stings
