Answer:
a. Blind FTP
Explanation:
According to my research on information technology, I can say that based on the information provided within the question in this case you should use Blind FTP. This is a file transfer protocol in which the user cannot see the names of the files that the server contains. Instead they can only download the files that they already know exist within the server. This allows you to keep all the files safe in the directory without having to worry about people accessing or downloading files that they shouldn't
