The median is a better measure of center when there is an outlier which will make the mean not be a good estimate of the center. Option B has $1075 as an outlier (i.e. it is far away from the other data sets). Hence, the median will be a better estimate of the center. Similarly, 94 is an outlier in option C and hence, the median is a better estimate. Options A and D has no outliers, making the mean a good estimate of the centre.
