Which of the following instruction tells the computer to close the current form in Visual Basic?

The correct answer is: A. This.Close()

The This keyword refers to the current form. The Close() method closes the form.

The other options are incorrect because:

• Me is also a keyword that refers to the current form, but it is not necessary to use it when calling the Close() method.
• Close.this() is not a valid Visual Basic statement.
• Close() is a valid Visual Basic statement, but it does not close the current form. It closes the form that is passed as an argument.

Here is an example of how to use the This.Close() method:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Close()
End Sub

This code will close the form when the user clicks the button.
