Answer:
B. He is frightened
Explanation:
At the beginning, it states that "Michael ran as fast as he could until he no longer heard footsteps following him." That he is running from something, and the description of the setting is kind of scarry, like "the staff was usually at the front desk. . .no one around. Silence engulfed the room. . .an uneasiness." At the end, it states that Michael gasped, so he is frightened in the passage.
