Keep in mind that breach of information during on-line survey could be the researcher's fault or subject's fault, depending on how they secure their internet connection.

- Method A is not suitable because of this phrase:   'confidentiality cannot be assured' .  This will make the subject thinks that the researchers are not taking responsibilities in protecting the information.

-Method B is not suitable because it create a physical location where people could come in and directly steal the data of all the subjects,

- Method C is not suitable because it does not educate the subjects with the possibilities that they can personally made the mistake that can cause the breach of information.

- Method D is the most suitable because it conveys that the research team is making their full efforts to ensure the anonymity of the subjects and also educate them regarding the possibilities of breach information from the subject's mistake.
