The correct option is : no mode
Explanation
The given data set is:
![9, 15, 86, 13, 16, 101, 85, 10, 14, 17, 102](https://img.qammunity.org/2019/formulas/mathematics/high-school/trpp35pihpf4ekm9v5ru1ikexnd6oligft.png)
The mode is the number that is repeated more often than any other number in the data set.
But here we can see that all the numbers in this data set are different. That means they appear only once.
So, there will be 'no mode' in this set.
