问题如下：
Select the internal credit enhancement that seeks to improve the overall credit quality of a risky pool of securitized loans.
选项：
A.Letters of credit
Overcollateralization
Cash collateral accounts
解释：
The correct answer is B. Overcollateralization, one of the three main types of internal credit enhancements used in securitization transactions, is a provision that the collateral underlying the transaction is larger than the face value of the issued bonds. The extra collateral provides a cushion to cover losses from defaults in the underlying pool of collateral. A and C are incorrect because both are types of external, not internal, credit enhancements.
