Step-by-step explanation:
The correct answer is a) SQL. SQL stands for Structured Query Language, and it is a domain-specific language (DSL) designed specifically for managing data in relational database management systems. It is used for tasks such as creating and modifying database schemas, querying and retrieving data, and performing other data manipulation operations.
SQL is used by database administrators, data analysts, and software developers who work with relational databases. It provides a standardized way to communicate and interact with databases, regardless of the specific database management system being used (e.g., MySQL, Oracle, SQL Server).
Some examples of SQL queries include SELECT to retrieve data from a table, INSERT to add new data, UPDATE to modify existing data, and DELETE to remove data.
