What programming language is commonly used to run queries on databases?

• A. HTML
• B. Standard Query Language (SQL)
• C. Python
• D. Java

Answer: (B)

The main idea is identifying the language used to query databases. SQL is the language specifically designed for this purpose in relational databases. It lets you ask questions about the data and perform operations like selecting rows, filtering results, and updating or deleting records. Its declarative nature means you specify what data you want, and the database figure out how to retrieve it.

HTML is a markup language for structuring web content, not for querying data. Python and Java are general-purpose programming languages; they can interact with databases and run queries, but they aren’t the language used to perform the queries themselves. So SQL is the best fit for running queries on databases.
