The correct answer is: C. Virtual, magnified and erect.
A simple microscope is a device that uses a single lens to magnify an image of an object. The image formed by a simple 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 lens. A virtual image cannot be projected onto a screen.
An erect image is an image that is upright, or right-side-up. A virtual image is always erect.
A magnified image is an image that is larger than the object being viewed. The amount of magnification is determined by the focal length of the lens.
The image formed by a simple microscope is always virtual, erect, and magnified. This is because the lens of a simple microscope is a converging lens. A converging lens causes light rays to converge, or come together, at a point behind the lens. The image formed by a converging lens is always virtual, erect, and magnified.
