One proven risk of gm crop is?
a. the escape of gm genes into non-gm crops.
b. the risk of cancer associated with eating gm food.
c. increased resistance of insects to pesticides because of the pesticides resistance of gm crops.
d. the loss of consumer support.

The only answer can be a. The escape of GM genes into non-GM crops. There is no evidence supporting that genetically modified crops cause mutation into cancer in the consumer. GM crops are altered not to be resistant to pesticides, but to be resistant to the best themselves, eliminating the need for spray on pesticides which the organisms might become accustomed to. The only reason why consumer support may be lost is due to myths and people who cause a fuss about genetically modified produce. There is no scientific evidence that the crops have negative effects. There is an idea of conservation related to harlume crops, because GM crops will be the dominant DNA should the plants breed which is why the answer is A.
