I'm pretty sure the answer is the third one!
Answer:
"The man ignored us and pressed on steadily."
Explanation:
By narrating from a first person point of view, the reader can experience the story as if he was in the narrator's shoes. In this type of point of view, the narrator refers to him or herself, therefore "I", "me", "my", "mine", "we", or "us", is used. This is characteristic of autobiographies for example, where we know the narrator's feeelings and thoughts from first hand. The other characters' feelings or thoughts can only be interpreted by the narrator but not known completely.
In this case the narrator uses us, which means he is the one telling the story from his/her perspective.
