when we declare the variable in a Particular control of vb then it is . . . . . . . . variable .

A static variable is a variable that is declared outside of any functions or procedures. It is accessible from all functions and procedures in the class.

A public variable is a variable that is declared with the Public keyword. It is accessible from all code in the project.

A general variable is not a valid option.

Here is an example of a local variable:

Sub MySub()
Dim x As Integer
x = 10
End Sub

In this example, the variable x is declared inside the MySub procedure. It is only accessible from within that procedure.

Here is an example of a static variable:

Class MyClass
Private x As Integer
Public Sub MySub()
x = 10
End Sub
End Class

In this example, the variable x is declared inside the MyClass class. It is accessible from all methods in the class.

Here is an example of a public variable:

Public x As Integer

In this example, the variable x is declared with the Public keyword. It is accessible from all code in the project.
