Hemerocallis sp. plants typically carry a negative electrical charge, while bees and other pollinators tend to accumulate a positive charge. Given that negatively and positively charged objects attract, a research team hypothesized that the difference in charges could attract the plant’s pollinators to the Hemerocallis sp. stamens. Based on the team’s experiments, the hypothesis was well supported for positive charges above a certain threshold. The team found that foraging honeybees exceeded that threshold, which suggests that __________

Which uses data from the graph to complete the text?

A

red mason bees can also attract the stamens.

B

red mason bees and European peacock caterpillars, with greater maximum charges than foraging honeybees have, cannot attract the stamens.

C

European peacock caterpillars tend to repel the stamens.

D

the threshold positive charge for a pollinator to attract the stamens must be greater than 100 pC.
