What cipher system did the Germans use to transmit Enigma encoded messages?
A
Caesar Cipher
B
Morse code
C
Keypad Cipher
D
Telephone
Explanation: 

Detailed explanation-1: -The Enigma machine is a cipher device developed and used in the early-to mid-20th century to protect commercial, diplomatic, and military communication. It was employed extensively by Nazi Germany during World War II, in all branches of the German military.

Detailed explanation-2: -## Introduction to the Enigma The Enigma machine implemented a *substitution cipher*, which encrypts a message by substituting one character for another. Such ciphers go back at least as far as Julius Caesar, who used a simple substitution cipher to encrypt military orders.

Detailed explanation-3: -Enigma was a cipher device used by Nazi Germany’s military command to encode strategic messages before and during World War II.

Detailed explanation-4: -With the help of captured Enigma material, and Turing’s work in developing a technique he called ‘Banburismus’, the naval Enigma messages were able to be read from 1941. He headed the ‘Hut 8’ team at Bletchley, which carried out cryptanalysis of all German naval signals.

Detailed explanation-5: -Each Enigma operator had a book of codes – a different one for each day – which instructed them on how to set up the machine for that day. Once a coded message was produced by one machine, it was sent via Morse code to an Enigma operator based elsewhere.
