Which of the following is not a benefit of genetically-modified seeds?

A) They often result in greater crop yields.
B) They could lead to food that lasts longer.
C) They are unable to cross-pollinate with other plants.
D) They have not been shown to negatively impact consumer health.
E) They enable crop resistance to pests such as bugs.

Genetically-modified seeds do have benefits such as enabling crop resistance to pests, resulting in greater crop yields, and potentially leading to food that lasts longer. There is no evidence to suggest that they negatively impact consumer health. However, they are not unable to cross-pollinate with other plants. In fact, there have been concerns about cross-pollination between genetically-modified crops and non-modified crops, potentially leading to unintended consequences.
