Answer:B. Encryption.Explanation:Encryption encrypts data so that it can not be understood if/when it is intercepted by a third party between the sender and the recipient.For example, if you're encrypting via the keyword vanilla, and then sending an email to Bob saying "Hi Bob", it would get encrypted as something like Vjh D5xx. The recipient would then use the keyword vanilla to decrypt this message so they can read it as Hi Bob. Anyone who intercepts this wouldn't have the keyword, and would just see incoherent letters, numbers, and symbols that they couldn't make heads or tails of.
