Answer:
A. True.
Step-by-step explanation:
The word Steganography is from the Greek word "Steganographia" where "Stego" means cover or concealed and "Graphia" means text/writing.
Steganography can be defined as data that is hidden within data. This simply means that, it is a cybersecurity technique used to hide information in another information and concealing the fact that a communication is in action or taking place.
In Computer science, Steganography is an encryption technique which is used alongside cryptography to cover or conceal the existence of a message (text) and render it un-intelligible to outsiders by transforming the message (text). Therefore, it is generally considered to be an extra-secure method to protect data from unauthorized access, use or piracy of copyright information. It is commonly used for audio, video and image files.
Hence, Steganography renders the message un-intelligible to outsiders by hiding it in a picture or other document.
