There are three plillars under Basel II, which of the following is not included in Pillar 2? 

选项：

Banks are required to carry enough capital to exceed the sum of the credit risk charge, the market risk charge and the operational risk charge.

Banks need a process for assessing their overall capital adequacy.

Supervisors should check the banks' compliance with Plillars 1 and 3.

Supervisors should expect banks to operate above the minimum regulatory capital ratios and should have the ability to require banks to hold capital in excess of the minimum.

解释：

A is correct.

考点：Basel II 中Pillar2 的内容

解析：A选项是pillar 1的内容（capital requirement）。

pillar 2也就是The Supervisory Review Process。包含了BCD中的要求。
