C错的地方，原文讲义在哪里？

选项：

An IPS sets the assets allocation strategy for client.

An IPS can only work for a long-term horizon client.

An IPS can make the risk objectives in line with the return objectives.

解释：

A is correct.

Strategic asset allocation is a part of IPS which clarify the investors' best asset allocation according to return and risk objectives. IPS is applicable for various time horizon, not only the long-term client. The return objective should be determined by risk objective, not like the statement in C.
