B because he knows he can see something when he is almost home
Answer:
Samuel most likely has audience anxiety
Reason:
If Samuel doesn’t normally have this issue any other time than its most likely not trait or context anxiety since he doesn’t really have a problem with public speaking. It’s also probably not situation anxiety which is where the person’s psychological reaction may be from it knowing the person or context.
One great example of suspense in the Hobbit is when Bilbo is in Smaug's smoky, gold encrusted lair, trying to find the sparkling cup, without awakening the dragon. A few times, we see the dragon release a puff of smoke, or stir, and Bilbo stops abruptly, than tiptoes forward quietly. There is so much suspense here while we await his fate!!
