In the Caesar cipher example, which step is the final encryption step?

• A. A Caesar shift of 7.
• B. Reverse alphabet substitution.
• C. Atbash-style swap.
• D. A Caesar shift of 14.

Answer: (D)

In a Caesar cipher, you encode by moving every letter forward by a fixed number in the alphabet. The final encryption step is the last shifting action that turns the plaintext into ciphertext. In this example, that last action is applying a shift of 14 to each letter, so that is the final encryption step. If there were an earlier shift (like 7), it would be part of the process before the last step, but the ultimate encryption is the 14-shift. The other options describe different techniques (like reversing the alphabet or Atbash-style swaps) that aren’t part of the Caesar cipher’s final encryption step.
