Final answer:
The claim is false; the Vigenère Tableau is a polyalphabetic cipher, and the One Time Pad uses a unique key for each character, making neither of them monoalphabetic ciphers.
Step-by-step explanation:
The statement that the Vigenère Tableau and One Time Pad are examples of Monoalphabetic Ciphers is False. Monoalphabetic ciphers use a single substitution alphabet throughout the entire encryption process. The Vigenère cipher, however, is actually a polyalphabetic cipher because it uses multiple substitution alphabets. Specifically, it applies a different alphabet based on a repeating keyword. The One Time Pad is also not a monoalphabetic cipher; it is an encryption technique that uses a single-use pre-shared key the same size or longer than the message being sent. Since each character in the plaintext is encrypted with a different key, it does not rely on a single alphabet for the substitution and therefore is unrelated to monoalphabetic ciphers.
