Plaintext: FAST AND THE FURIOUS. Using Vigenere Cipher and the key: CARS.24. Encrypt the word 'FAST'Group of answer choicesHAJLHJALHLAJHALJ

To encrypt the word 'FAST' using the Vigenere Cipher and the key 'CARS', follow these steps:

1. Write down the text you want to encrypt ('FAST') and the key ('CARS'). If the key is shorter than the text, repeat it until it matches the length of the text. In this case, the key is longer than the text, so we only use the first four letters.

2. Convert each letter of the text and the key to their corresponding numerical values (A=0, B=1, ..., Z=25). For 'FAST', we get [5, 0, 18, 19]. For 'CARS', we get [2, 0, 17, 18].

3. Add the numerical values of the text and the key together, modulo 26. This means if the sum is greater than 25, we subtract 26 from it. We get [7, 0, 9, 11].

4. Convert these numerical values back to letters to get the encrypted text. [7, 0, 9, 11] corresponds to 'HAJK'.

So, the word 'FAST' encrypted using the Vigenere Cipher and the key 'CARS' is 'HAJK'.
