Ответ:
Precision is described by the number of significant figures in a measured value. This would suggest that C is the answer.
Accuracy is a measure of how close a measured value is to the actual thing it's measuring. A and B would be the answer to this question.
D isn't the answer to anything, as multiple samples are needed.
