None of the choices work. Are you sure these are the correct choices for this problem?

yes

Then I don't know how this works.
You have 188 ft of fencing.
The first answer, for example, is 89 x 99. 89 + 99 = 188. Just fencing two sides takes up all your fencing material. What happens tot he other two sides of the rectangle?

Is there a figure showing the garden that shows that two sides do not need fencing?

I still don't understand how this problem works, but if you must pick an answer, then choice C has the largest area, doesn't it?
