Thank you for the opportunity to help you with your question!

The answer is B.

If AB=9 then AF=9 as these segments are congruent.

If FE=22 then DE=22 as these segments are congruent.

These are properties of an incircle within a triangle.

CE = CD + DE = 22+12 = 34

AE = AF + FE = 9+22 = 31


Please let me know if you need any clarification. I'm always happy to answer your questions.
