Answer 1

The scenario described is an example of a Client-Server model where a user sends an SQL statement to a server, which then processes and returns the result.

Step-by-step explanation:

The question refers to a scenario where a user sends an SQL statement from a client to the server, and the server sends back the result. The correct option that describes this scenario is A. Client-Server. In a Client-Server model, the client is usually an application that the user interacts with to send requests to a server. The server then processes these requests, which often involve SQL queries to a database, and sends the results back to the client. The server performs the backend tasks such as executing the SQL statements, retrieving data, and then sending this data to the client to be displayed or further used by the user.
