Answer: D) The author uses descriptive details and a second-person point of view to effectively describe the experience.
Step-by-step explanation: when narrating a story or making a description, we can use different perspectives according to the impact we want to make, we can use first person (using the pronouns "I" or "we"), second person (using the pronoun "you") and third person perspective (using the pronouns "he," "she," "it" and "they"). In the given excerpt the author uses a second-person point of view ("If you are sitting in the gallery you will have a clear view of the stage as it projects out from the far side of the round enclosure") and also uses descriptive details to effectively describe the experience.
