Question
19. Which of these is not a valid built-in data type in Visual Basic:
Correct Answer
Option D is the correct answer.
Detailed Explanation
Variable is not a data type; it's a container for storing data of a specific type. Integer, Boolean, String are built-in types. Array is a data structure, not a primitive type, but it's a type. Variable is definitely not a built-in data type.
Hint
Variable is a concept, not a type like Integer or String.
