Answer:
The correct answer is the option D: present her with data showing that the pool is not only needed but also affordable and practical.
Explanation:
To begin with, due to the fact that Ms Wheterby is new to the system of the school it will not be nice to compliment her about her leadership due to the fact that she may not acted much in the time she was there and because Matthew does not know her that much too, therefore that the best way to approach to her is to show her that the pool is a big deal and can not only be needed but also affordable and practical for the students in order to achieve better goals as well as increase the reputation of the school. And in order to do that Matthew will need good data.
