The correct answer is: A. Magnified, virtual, erect image.
A microscope is an instrument used to magnify small objects. It uses a combination of lenses to create an enlarged image of the object. The image formed by a microscope is always virtual, erect, and magnified.
A virtual image is an image that is formed by light rays that do not actually intersect. Instead, the light rays appear to come from a point behind the mirror or lens. A virtual image is always upright, or erect. A magnified image is an image that is larger than the object itself.
The image formed by a microscope is always virtual, erect, and magnified because of the way that the lenses in the microscope work. The objective lens focuses the light from the object onto the eyepiece lens. The eyepiece lens then magnifies the image formed by the objective lens.
The image formed by a microscope is useful for viewing small objects that cannot be seen with the naked eye. It is also useful for measuring small objects.
