Answer 1

The correct option is D Median

The mean is $68.5$, the median is $61$, and the mode is $40$ for this data set. The median is the best measure, as t he data set contains some extremely high values as outliers, which are $142$ and $85$. Therefore, the mean is higher than most of the numbers of the data set.
