Answer:
b. ENCRYPTION
Step-by-step explanation:
Encrypted data is commonly referred to as ciphertext, while unencrypted data is called plaintext.
Encryption is a process that encodes a message or file which makes it to be read by certain people only.
Encryption uses an algorithm to scramble, or encrypt, data and then uses a key for the receiving party to unscramble, or decrypt, the information.
Encryption is the option required to prevent users from examining the SQL code.
