Answer: Loss-aversion bias

**Explanation:** - **Hindsight bias (A)** is a cognitive error, which can often be corrected or eliminated through better information, education, and advice. It refers to the tendency to view past events as having been predictable. - **Loss-aversion bias (B)** is an emotional bias, making it more difficult to correct. Emotional biases stem from impulses and intuitions, and while they can be recognized, they are harder to mitigate. Loss-aversion bias describes the preference for avoiding losses over achieving gains. - **Representativeness bias (C)** is also a cognitive error, similar to hindsight bias, and can often be addressed through improved information and education. It involves classifying new information based on past experiences. **Conclusion:** Emotional biases, such as loss-aversion bias, are inherently harder to correct compared to cognitive errors, making **B** the correct answer.
