A. R
B. Python
C. SQL
D. SAS
Answer
C. SQL
Explanation
SQL, or Structured Query Language, is a standard language specifically designed for managing data in RDBMS. It allows you to query, update, and reorganize data, as well as create and modify the schema (structure) of a database system and control access to its data. SQL has a concise syntax that allows for powerful, complex queries that specify the criteria of the data to be retrieved.
While R, Python, and SAS can interact with databases, they require additional libraries or packages to do so, and they are not as efficient or straightforward for this specific task as SQL. These languages are more commonly used for data analysis and manipulation once the data has been extracted from the database.
