The results are precise but not accurate. Option B.

Precision and accuracy

Precision refers to the closeness of repeated measurements to each other. In other words, it is the consistency of measurements.

Accuracy, on the other hand, is the closeness of measurements to the true value.

Looking at the measurements made by the researcher, the repeated measurements are close to each other, only ranging between 55.99 and 56.13. Thus, the researcher is precise in his measurement.

The true value is 60.10. This is significantly different from the measurements of the researcher. Thus, the researcher is far from being accurate with his measurement.
