The main property of . . . . . . . ., is LoadPicture and resize the picture .

The correct answer is A. Picture.

The LoadPicture property loads a picture into a PictureBox control. The Resize property resizes a PictureBox control.

The Text property is used to set or get the text displayed in a TextBox control.

The List property is used to get or set the list of items displayed in a ListBox control.

The Form property is used to get or set the form that contains the control.

Here is a code example that shows how to use the LoadPicture and Resize properties:

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

'Load a picture into the PictureBox control Me.PictureBox1.LoadPicture("C:\Users\YourUserName\Pictures\MyPicture.jpg")

'Resize the PictureBox control to fit the picture Me.PictureBox1.Size = Me.PictureBox1.Image.Size

End Sub ```

I hope this helps!
