参考答案:  B


本题详细解析:
B

Adverse selection refers to a situation where one party has more information about their own characteristics, risks, or behavior than the other party during the transaction. This information asymmetry can lead to an imbalance in the selection of goods, services, or insurance contracts, as those with higher risks or undesirable characteristics are more likely to participate.\

Moral hazard (Choice A) arises when one party alters their behavior or takes on more risks due to the presence of insurance or a contract, knowing that they will not bear the full consequences of their actions. Moral hazard is another problem associated with asymmetric information.

Choices C and D are private responses to the problems associated with asymmetric information.
