Answer 2

To transform the original message to an unintelligible message by some logic, (b) Cipher is used.

A cipher is any sort of algorithm or code applied repeatedly to the various components of a message than needs to be encoded. The first instance in known history of a cipher being used was by Julius Caesar of Rome. He used ciphers to transfer secret messages between his troops during wars with the tribes of Rome. Ciphers gained particular importance during the world wars in the early and mid 20th century. Since warring countries needed a secure way to communicate without their enemies getting to know their plans, ciphers were in common use.
