A concave mirror of focal length `2 cm` is placed on a glass slab as shown in the figure. The image of point object O formed due to reflection at mirror and then refraction by the slab

Will be virtual and will be at 2 cm from the pole of the concave mirror

Will be virtual and formed on the pole of the mirror

Will be real and on the object itself

None of these
