Find the correct mirror image of the given figure containing an upright triangle with a small shaded triangle inside its bottom-right corner when a vertical mirror is placed to its right:

When an object is reflected across a vertical mirror line placed to its right side, the left and right positions are interchanged, while the top and bottom orientations remain constant.
* The main upright triangle looks identical in reflection.
* The small shaded inner triangle, which was originally at the bottom-right corner, reflects over to become positioned at the bottom-left corner. This corresponds to Option B.
