A substitution cipher may be monoalphabetic or polyalphabetic: A single alphabet is used to encrypt the entire plaintext message.

Detailed explanation-3: -The vigenere cipher is an algorithm of encrypting an alphabetic text that uses a series of interwoven caesar ciphers. It is based on a keyword’s letters. It is an example of a polyalphabetic substitution cipher.
