请问这道ETHICS的题目 having, purpose, company, exchange, commercial

liaowang1989

As the Managing Director of a commercial bank, a CFA charterholder sat in on a
board meeting of a publicly listed company that the bank had lent a large sum of
money. The purpose of the board meeting was to renegotiate the terms of the
commercial loan due to the pending restructuring of the company. The next day
all of the Managing Director’s shares of the publicly listed company are sold on
the stock exchange, the sell order having been given two days prior to the
meeting. According to the Standards of Practice Handbook, the CFA
charterholder was least likely in violation of which CFA Institute Standards of
Professional Conduct?
A. Disclosure of Conflicts.
B.  Priority of Transactions.
C.  Material Nonpublic Information.

为何这道题目选B?而不是C,MD先交易了自己的账户，可能和投资账户无关，但是C应该也没有违反条例，这个出售指示在开会两天前就提交了，所以没有用到未公开重大消息。
请教！

- The CFA works as the Managing Director of a commercial bank
- Shares of the publicly listed company are sold on
the stock exchange

base on these statements , seems got nothing to do with B , so least likely B is in violation

我的理解是，，这个跟public和nonpublic information没关系啊。而且share of public并不是关于information。。。所以B更符合
