Solution

The correct option is A
Accuracy reflects how close a measurement is to a known or accepted value, while precision reflects how reproducible measurements are, even if they are far from the accepted value. Precision is independent of accuracy. That means it is possible to be very precise but not very accurate, and it is also possible to be accurate without being precise.
Here the darts in dartboard are very close to each other but not hitting the accuracy ie. the bullseye, hence the darts are precise ( close readings) but far from accuracy or quite away from accuracy.
