Substitution and transposition.
stream ciphers and block ciphers
To accurately answer your question, I would need to know the specific options you are referring to. However, generally speaking, a cipher is a method of transforming text to secure its content. Common types include substitution ciphers, transposition ciphers, and block ciphers. If an option does not involve any form of text transformation or encryption, it would likely not be considered a type of cipher.

Yes Benjamin Franklin invented ciphers and codes
Cryptology is the study of codes and ciphers while cryptography is the creating of codes and ciphers.
Hebrew scholars made use of simple monoalphabetic substitution ciphers around 500 to 600 BC.
There are many different algorithms used in cryptography - RSA, DES and Rabine ciphers are a few that can be used - as well as others that are used to help determine the constants in a system like Euclid's algorithm.
To compare cryptography and cryptology we must understand that they are about coding and ciphers. To contrast them, we must understand that cryptography involves the creation of codes and ciphers while cryptology is the study of them.
Encryption and decryption algorithms are called ciphers in cryptography
