    • A.

      Not safe

    • B.

      Safer

    • C.

      Blocked

This encryption ensures that sensitive information, such as passwords or credit card details, cannot be intercepted or accessed by unauthorized individuals. Therefore, a website starting with "HTTPS" is considered safer compared to a website using the regular "HTTP" protocol.

    The strongest password would include:

    • A.

      Upper- and lower-case letter, numbers and symbols

    • B.

      A long sequence of numbers

    • C.

      An important date

    • D.

    Correct Answer
    A. Upper- and lower-case letter, numbers and symbols
    Explanation
    The strongest password would include upper- and lower-case letters, numbers, and symbols because this combination increases the complexity of the password and makes it harder for hackers to guess or crack. Including a long sequence of numbers, an important date, or the user's last name alone would not provide the same level of security as they are easier to guess or obtain through personal information.
