Answer:

(B) Her results are both precise and accurate.

Explanation:

In Chemistry, Accuracy refers to how close a measurement is to it's standard value or known value. On the other hand, Precision means how close two measurement are to each other regardless whether the results are accurate or not.

In the above question, all the above results are very close to each other. That's why the results are Precise to each other. All the results  are close enough to the actual value of the experiment. That's why the result are also accurate.
