The correct answer is C. QBE.
QBE stands for Query by Example. It is a query language that allows users to select data from a database by filling in a form. QBE is a very intuitive language, and it is easy to learn and use.
SQL stands for Structured Query Language. It is a programming language that is used to manage data in relational databases. SQL is a very powerful language, but it is not as intuitive as QBE.
Xbase is a programming language that is used to create and manage databases. Xbase is not as popular as SQL or QBE, but it is still used by some businesses.
XML stands for Extensible Markup Language. It is a markup language that is used to create documents that can be shared and processed by different applications. XML is not a query language, and it cannot be used to select data from a database.
