中文解析：协会规定的例外有4条，分别是：Basic integrity of the model，Model accuracy could be improved，Intraday 和 Bad luck，只有B选项的两点都属于这4条例外之中。
The committee established four categories of causes for exceptions and guidance for supervisors for each category:
(1) Basic integrity of the model: The deviation occurred because the positions were reported incorrectly or because of an error in the program code. (The penalty should apply)
(2) Model accuracy could be improved: The deviation occurred because the model does not measure risk with enough precision (e.g., has too few maturity buckets, The penalty should apply).
(3) Intraday: Positions changed during the day (The penalty should be considered)
(4) Bad luck: Markets were particularly volatile or correlations changed.
the data sample is too small不就是（2）里的has too few maturity buckets？有什么区别吗？
