Which term refers to the symbolic names used in code to reference data and operations?

• A. Literals
• B. Keywords
• C. Operators
• D. Identifiers

Answer: (D)

Identifiers are the symbolic names used in code to reference data and operations. They let you label variables, functions, classes, constants, and other elements so you can work with them by a meaningful name rather than a raw value or memory address. For example, names like speed, totalCost, or computeTotal() serve as identifiers you use throughout the program to access the corresponding data or behavior. They follow the language’s naming rules (letters, digits, underscores, not starting with a digit) and are distinct from literals (actual values like 5 or "hello"), keywords (reserved words with special meaning), and operators (symbols like + or -). So the best term for these symbolic names is identifiers.
