9 Based on the final section of Tolmach’s report, the Plan should use:
选项：
A. a liability-based benchmark.
B. an absolute return benchmark.
C. a manager universe benchmark.
解释：
A is correct.
Based on the Plan’s type (defined benefit) and its characteristics as detailed in the final section of Tolmach’s report, a liability-based benchmark is most appropriate. Liability-based benchmarks are used most frequently when assets are required to pay a specific future liability, as in a defined benefit pension plan.
