选项： Jurisdictional fragmentation, increased
counterparty risk, less transparency, and standardization.
Product complexity, illiquid products, presence ofwrong-way risk, and lack of standardization.
C.Illiquid products, jurisdictional fragmentation, presence of wrong-way risk, and legal concerns.
D.Lack of standardization, increased counterparty risk, increased dependency risk, and less transparency.
解释：
B Lack of standardized products, complexity, illiquid products, and presence of wrong-way risk are characteristics of OTC derivative products that make CCP clearing challenging. OTC derivative products need to be standardized before they can be cleared through a CCP. More complex and illiquid derivative products are problematic for CCPs because their unique features make them difficult to value. Products with wrong-way risk are also more complex and create additional concerns for the added risk to CCPs in the event of default.
CCP的存在不是会提高标准化，从而提高市场的流动性吗？那为什么standardization会是 challenge呢？
