Concept:Encryption is the process of converting readable data into a coded format, so that only the intended receiver can view the original information.
Explanation:Encryption uses a key or algorithm to scramble a message before it is sent.
Only the authorised recipient, who has the correct decryption key, can unlock and read the message.
If a third party intercepts the data during transmission, they will only see the scrambled or unreadable format.
As a result, the confidentiality of the information is maintained throughout its journey.
This means encryption protects the message from source to destination, preventing unauthorised access.
Answer:Option C: Safe delivery of messages to destination without being accessed by a third party.
