Explanation:

A round character is complex and shows multiple emotions. King Claudius showing a range of emotions (including guilt) fits this. Representing an idea (religious devotion) is flat. Deciding to step down (not in text) and behaving same (no development) don't show roundness.

Answer:

He shows a range of emotions, including guilt.
