Final answer:
The correct answer is 'd. accurate' because accuracy refers to how close a measurement is to the correct or accepted value, while precision is about the reproducibility of measurements.
Step-by-step explanation:
A measurement that closely agrees with accepted values is said to be accurate. This is because accuracy in measurements refers to how close the measurement is to the correct or accepted value. Comparatively, precision refers to the reproducibility of measurements, meaning that if you were to repeat the measurement multiple times, the results would be very similar to each other, but not necessarily close to the true value. A clear example is found in archery: if all arrows land in the same spot but away from the bullseye, the shots are precise but not accurate. However, if they all land on the bullseye, they're both precise and accurate. Thus, when a measurement aligns with the true value, it can be considered to be accurate.
