The correct answer is B. Confidentially
Step-by-step explanation:
In business, confidentiality refers to the responsibility of financial institutions, corporations, and people in them to protect the information provided by clients. This principle is one of the most important in the Code of Ethics and implies institutions, companies or their employees do not use information from clients inappropriately and guarantee information cannot be obtained by other people or companies.
This is the principle Jason is following because by using a password-protected folder to keep the information of his clients he guarantees the information is not accessed by external entities and therefore it is not used for unethical purposes.
