选项：

A.

absence of style drift.

investment process may not be repeatable.

manager should be included in the universe of potential managers.

解释：

Correct Answer: B

The results of the returns-based style analysis and the holdings-based style analysis should be consistent with the philosophy of the manager and the investment process. If this is not the case, it may suggest that the process is not repeatable or not consistently implemented. For these results the manager should not be included in the universe of potential managers, whereas if the results track over time they may suggest style drift.
