Answer:
A) to create an image of Dr. Heidegger's movements
Explanation:
The words "hobbled" is used to refer to someone who is struggling, strangely or uncomfortably. The author used our word so the reader could understand how Dr. Heidegger was doing. Thus, it is possible for the reader to understand that Dr. Heidegger did not walk normally, because one of his legs did not work perfectly. For this reason, we can conclude that the word "hobbled" was used to create an image of Dr. Heidegger's movements.
