What is the primary purpose of encryption in email communications?

• A. To compress files
• B. To ensure only the intended recipient can read it
• C. To store emails efficiently
• D. To provide a backup

Answer: (B)

The primary purpose of encryption in email communications is to ensure that only the intended recipient can read the message. Encryption transforms the original content of the email into a coded format that is unreadable to anyone who does not possess the correct decryption key. This process protects sensitive information from unauthorized access, which is critical in maintaining confidentiality and security in communications. Other options do not align with the function of encryption. For instance, compressing files is about reducing file size for storage or transmission efficiency, while storing emails efficiently relates to how they are managed or archived without ensuring their content remains private. Additionally, providing a backup refers to creating copies of data to prevent loss, which is unrelated to the security measures encryption provides.
