This dialogue is about asking for and giving directions. Let's figure out the logical order:
Therefore, a logical flow would be someone asking for clarification, then receiving directions, and finally thanking the person.
1. A. On my left? (Could be a response to 'Is it on your left?' or asking for confirmation.)
2. C. Yes, sure. Go down Red Street and turn left. (This provides the directions.)
3. B. Thank you. (This is the response after receiving directions.)
Order: A, C, B
