A. The scale is accurate but not precise.

B. The scale is precise but not accurate.

C. The scale is neither precise nor accurate.

D. The scale is both accurate and precise.

Then you need to tell the difference between accuracy and precision.

Accuracy refers to the closeness of the measure to the real value, while precision, in this case, refers to the level of significant figures that the sacle report.

The fact that the scale reports the number with 4 significant figures means that it is very precise, but the fact that the result is not so close to the real value as the number of significan figures pretend to be, means that the scale is not accurate.

So, the answer is that

B. The scale is precise but not accurate
