Given the analogy: Delusion : Hallucination :: Chagrin : ?
Let's analyze the relationship between the pairs:
- Delusion and Hallucination are both types of false perceptions or experiences, often related to the mind. A delusion is a false belief, while a hallucination is a false sensory experience.
- Similarly, Chagrin is a feeling of distress or embarrassment caused by failure or disappointment.
Therefore, the word that closely matches the meaning or is related to Chagrin is Annoyance, which refers to a feeling of irritation or displeasure.
Conclusion:
The correct substitute for the question mark is Annoyance.
