问题如下：

Increase the amount of which of the following can increase the management fee, until the committed capital is fully drawn down and invested?

选项：

A.invested capital B.committed capital C.assets under management

解释：

B选项正确。在承诺资本(committed capital)完全到位并投资前，管理费是基于承诺资本计算的，而非投入资本(invested capital), 所以提高承诺资本的金额可以提高管理费。
