An identifier is another word for

• A. the name of the variable
• B. a data type
• C. the memory address
• D. a reserved keyword

Answer: (A)

In programming, an identifier is the name you use to refer to something you define in code—like a variable, function, or object. For a variable, the identifier is its name. So when you write something like int score = 10;, score is the identifier that labels that storage location so you can read or modify it by name. The data type (int, float, etc.) describes what kind of value is stored, not what you call the variable. The memory address is where the value actually lives at runtime, which you don’t use as the label in your code. Reserved keywords are language-specific words with special meaning and can’t be used as variable names. keeping the identifier as the name of the variable is exactly what this describes.
