To determine the best description of the mood in an excerpt, it would be helpful to analyze the language, tone, and context provided in the passage. However, without the specific excerpt to reference, I can't provide an accurate answer.
If you can share the excerpt or provide more context about it, I can help you analyze the mood and select the most appropriate option from the choices given: gloomy and ominous, confining and restricted, light and optimistic, or disappointed and dismayed.
