{'mirror': [0, 0, 0, 1], 'concave': [0, 0, 0, 4], 'image': [0, 1, 3, 23], 'convex': [0, 0, 0, 6], 'plane': [0, 0, 4, 8]}

Option 1 states that the mirror could either be plane or convex. Let`s examine both possibilities.

1. Plane mirror: A plane mirror is a flat mirror with a smooth surface. When you stand in front of a plane mirror, your image appears to be the same size and distance as you are from the mirror. The light rays that hit the mirror are reflected at the same angle, resulting in a virtual image that appears behind the mirror. This virtual image appears erect, meaning it is oriented in the same way as the object.

2. Convex mirror: A convex mirror is curved outward and has a reflective surface on the outside. When you stand in front of a convex mirror, your image appears smaller and farther away than you actually are. The reflected light rays diverge, causing the virtual image to form. In a convex mirror, the virtual image also appears erect.

Based on this information, option 1 is correct. Both a plane mirror and a convex mirror would produce an erect image, regardless of the distance you stand from the mirror.
