Final answer:
Shared variables are used to transfer information between the database and the host-language.
Step-by-step explanation:
The correct option to transfer information between the database and the host-language is Shared variables. Shared variables are variables that can be accessed and used by multiple programs or modules. In the context of databases and host-languages, shared variables are used to pass data between the two, allowing them to communicate and exchange information.
For example, in a programming language like Java, you can declare a shared variable that represents a database connection. This variable can be used in different parts of the program to retrieve data from the database, update records, or perform other database-related operations.
