选项：
A. providingmore direct access to a wider range of assets.
B. reducingthe inherent credit risk of pools of loans and receivables.
C. eliminatingcash flow timing risks of an ABS, such as contraction and extension risks.
解释：
A is correct. Securitization allows investors to achieve more direct legal claims on loans and portfolios of receivables. As a result, investors can addto their portfolios exposure to the risk–return characteristics provided by awider range of assets.
B is incorrect because securitization does not reduce credit risk but, rather, provides a structure to mitigate and redistribute the inherent credit risks of pools of loans and receivables.
C is incorrect because securitization does not eliminate the timing risks associated with ABS cash flows but, rather, provides a structure to mitigate and redistribute those risks, such as contraction risk and extension risk.
