Answer: C. She gets progressively more comfortable as she approaches her childhood home.
The passage describes the narrator's physical reactions as she drives towards her childhood home. She exhaled twice when she crossed the state lines and exhaled again when she turned right on Kiln DeLisle Road, driving past her family's houses. These exhalations indicate a release of tension and anxiety, suggesting that the narrator is getting progressively more comfortable as she approaches her childhood home. Therefore, option C is the best inference supported by the passage. Options A, B, and D are not supported by the passage.
