Real image is always inverted.

A real image is formed when actual light rays converge at a specific point after passing through a lens or reflecting off a mirror. It is different from a virtual image, which is formed when light rays appear to diverge from a point but do not actually converge.

Characteristics of a real image:
- Inverted: A real image is always inverted, meaning it is upside down compared to the object being observed. This is because light rays cross over each other at the point of convergence.
- Enlarged or diminished: The size of a real image can vary. It can be either enlarged or diminished compared to the object, depending on the distance between the object and the lens/mirror and the focal length of the lens/mirror.
- Can be captured on a screen: A real image can be projected onto a screen or a surface where it can be observed and captured. This is the basis for the functioning of cameras and projectors.

Explanation:
- When light rays pass through a convex lens or reflect off a concave mirror, they converge to form a real image. The light rays from the top of the object converge to a point below the optical axis, while the rays from the bottom of the object converge to a point above the optical axis. As a result, the image is formed upside down.
- The inversion of the image can be observed by performing a simple experiment. Hold an object (e.g., a pencil) in front of a convex lens and observe the image formed on a screen placed behind the lens. The image will be inverted compared to the object.
- This inversion of the image is due to the way light rays interact with the lens or mirror. The lens or mirror bends the light rays in such a way that they cross over each other, causing the image to be inverted.
- In contrast, a virtual image is formed when light rays appear to be diverging from a point without actually converging. Virtual images are always erect and cannot be projected onto a screen. They are formed when the object is placed inside the focal length of a convex lens or when the object is closer to a concave mirror than its focal length.

Therefore, the correct answer is option 'C': Inverted.
