SQL and PL/SQL are languages used to access data within Oracle databases
A
Correct answer
Explanation
SQL is Oracle's standard query language for data manipulation and retrieval, while PL/SQL is Oracle's procedural extension to SQL that adds programming constructs like variables, conditions, and loops. Both are fundamental languages for working with Oracle databases - SQL for declarative data operations and PL/SQL for complex procedural logic. This statement accurately describes the two core languages used in Oracle database environments.
