Aperson tries to pour exactly one kilogram of sand onto a scale on five different occasions. the actual amounts he pours are shown below:
0.80kg, 0.90 kg, 1.0 kg, 1.1 kg, 1.2 kg
which of the following best describes his results

a. his results were very precise
b. while inconsistent, his average of 1.0 kg made his results quite accurate
c. his results were both precise and accurate
d. his results were very consistent
