Correct answer: D
The Vigenere cipher is a classic example of poly-alphabetic substitution because it uses multiple alphabets determined by a keyword. In contrast, the Caesar cipher is mono-alphabetic as it applies a fixed shift to every character. P-boxes and S-boxes are structural components of modern block ciphers, not standalone substitution examples.
