Final answer:
The adjectives and text provided indicate an effect of fear or anxiety, leading to the conclusion that the overall effect is one of trepidation. So, the correct option is d).
Step-by-step explanation:
The question asks about the overall effect achieved by using adjectives in a given paragraph. To determine the effect, we must look at the adjectives provided and the context in which they are used. Phrases such as 'anomalous species of terror', 'irrepressible tremor', and 'intense sentiment of horror', all suggest a powerful emotional response related to fear.
Moreover, the extracts from Poe and the discussion about tragedy and emotions both align with these sentiments. Terms like fearful, frightened, horrified, and trepidation reinforce this atmosphere. Therefore, the correct option that describes the overall effect is one associated with fear, which in this case is option (d) Trepidation, as it conveys a sense of fear or anxiety about something that may happen.
