Answer: E. There is no code of ethics, and the company has little regard for high ethical standards.
Explanation:
While all the options are good enough to impart one's decision to avoid this company, ethics is simply non-negotiable. This is a banking institution which means that they handle people's money. If they engage in unethical ways and show little regard for high ethical standards, people will be hurt directly.
In order not to be complicit in this, it is best to avoid the company because banking institutions without codes of ethics or adherence to high ethical standards never last long.
