Detailed explanation-1: -Hence, scrambling of data before transmission across a network to avoid manipulation by a third party is known as encryption. So, option (4) is correct.

Detailed explanation-2: -Scrambling is a digital encoding technique that is used in modern data communication schemes and can principally provide aid in retrieving information from received data enhancing synchronization between the transmitter and the receiver.

Detailed explanation-3: -Encryption is a way of scrambling data so that only authorized parties can understand the information. In technical terms, it is the process of converting human-readable plaintext to incomprehensible text, also known as ciphertext.

Detailed explanation-4: -Encoding: Reversible transformation of data format, used to preserve the usability of data. Hashing: A one-way summary of data that cannot be reversed and is used to validate the integrity of data. Encryption: Secure encoding of data used to protect the confidentiality of data.

Detailed explanation-5: -Scrambling data allows you to create test data based on production (or “live") data, but with the ability to change the values of certain fields. In this way, you can avoid sensitive or confidential information appearing in test data.
