Which of the following is used to define a variable in VBA?*1 pointPrivateSetDimPublic

To define a variable in VBA (Visual Basic for Applications), the correct keyword to use is Dim.

Explanation:

1. Dim: This statement is used to declare a variable and allocate storage space for it. The syntax is as follows:

   Dim variableName As DataType
   

   For example:

   Dim myVariable As Integer
   

2. Private: This keyword is used to declare a variable that is accessible only within the module (or class) in which it is declared. It is not used solely for defining a variable but for specifying its scope.

3. Public: This keyword declares a variable that can be accessed from any module or form within the program. Like Private, it does not specifically define a variable but indicates its visibility.

4. Set: This keyword is used to assign an object reference to a variable, especially for object types. It does not define a variable but is used in conjunction to assign a value.

Therefore, Dim is the correct answer for defining a variable in VBA.
