Answer 2

A. The range will increase by one

Explanation:

The range is the difference between the lowest and highest number in the data set.

In the data set 14 is lowest and 22 the highest with a difference (range) of 8.

If 13 is added this will be the lowest number and 22 still the highest - this will give a range of 9 so this is an increase by one
