Final answer:
B) Mark is caught by the Tsook and punished. Mark is caught by the Tsook and punished.
Step-by-step explanation:
The first time Mark tries to escape from the Tsook, he gets caught by them and is punished. In the given reference text, it mentions that when Gil-Dong opened the stone door and stepped inside, he found himself in an open plain surrounded by people who rushed towards him with evil intent. They questioned him and accused him of trespassing. This aligns with option B in the question, where Mark is caught by the Tsook and faces consequences for his escape attempt.
