Paragraph 5 makes all of the following claims about Bt resistance in insect populations EXCEPT: A. Regular use of Bt pesticides has not created resistant insect populations, so the use of Bt plants is probably safe as well. B. The evolution of Bt-resistant insect populations will happen eventually if use of transgenic plants becomes widespread. C. Because Bt plants are toxic at all times and in all tissues, they allow only Bt-resistant insects to survive and reproduce. D. Planting nontransgenic plants alongside Bt plants may help Bt-susceptible insects to remain part of the population.
