What is Plain Text?

Plain text refers to data that is readable without the need for decryption. This means that the information is presented in a straightforward, unformatted manner, and can be easily understood by anyone who possesses access to it. It is commonly found in documents, emails, and other forms of written communication that do not require any special software or processes to interpret.

In contrast, encrypted data, which is indicated in the first option, is transformed through an algorithm into a format that is not understandable without the correct key or method to decrypt it. The third option mentions data that is hidden and inaccessible, which does not apply to plain text as it is inherently accessible and can be viewed directly. The last choice refers to data stored in a secured database, which implies additional security layers and formats that go beyond plain text. Thus, plain text is best characterized as data that is directly readable, confirming that option B accurately describes its nature.
