AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.

The question asks for any two properties, but since it's 1 mark, state two concisely in one line. The key properties from the textbook are: virtual, erect, same size, laterally inverted, and image distance = object distance. Mentioning "virtual and erect" with the image distance (10 cm behind) covers the mark neatly. Examiners typically award 1 mark for any two correct properties.
