B. After the loan, Ali Small Loan Company will take punishment measures such as strict exposure and closing the online store account for the defaulting loan application e-commerce. The measures taken by Ali Small Loan Company during and after the loan effectively reduce the probability of moral hazard. C, D, before the loan, Alibaba Microfinance Company extracted data from the database, imported the credit evaluation model, analyzed the credit accumulated by the e-commerce applying for the loan, and introduced the cross-examination technology to accurately evaluate the repayment willingness and repayment ability of the e-commerce applying for the loan. This effectively reduces the probability of adverse selection.
