Final answer:
The statement describing the situational irony in 'The Storyteller' is that the prince’s mother took extreme action to protect her son from a highly unlikely danger, which reflects the unexpectedness and excessiveness of the caution.
Step-by-step explanation:
Looking at the provided excerpts from various literary works, these passages do not seem to relate directly to the initial question which refers to a specific excerpt from "The Storyteller." The situational irony in that passage arises from the expectation set by the prince’s mother to protect her son from an unlikely danger, that is, being killed by a sheep. Since the passage describes a proactive measure taken to protect against an improbable threat, the irony lies in the unexpected and unnecessary degree of caution.
