A student performs an experiment to determine the density of a sugar solution. She obtains the following results: 1.79 g mL^-1, 1.81 g mL^-1, 1.80 g mL^-1, 1.81 g mL^-1. If the actual value for the density of the sugar solution is 1.80 g mL^-1, which statement below best describes her results? A) Her results are precise, but not accurate. B) Her results are accurate, but not precise. C) Her results are both precise and accurate D) Her results are neither precise nor accurate. E) It isn't possible to determine from the information given.

The results are precise because they are all very close to each other, showing low variability. The results are also accurate because they are very close to the actual value for the density of the sugar solution. Therefore, the results are both precise and accurate.
