      D Attaching the file without any protection Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Encrypting the document or using encrypted email. When the document is encrypted, the underlying information is scrambled using cryptographic algorithms so that only someone with the corresponding decryption key can recover it.
