Answer:
C. It creates an atmosphere of mystery
Explanation:
The passage gives out a few clues:
1. two am
2. stealthy step
3. long black shadow
4. man with a candle
5. notice the 2 key words in the middle of the passage, stealthy and cautiously
(for reason #5 i'm sure they weren't pointed out for that reason, it's just something that I noticed and was a huge hint for me)
