How does a real image differ from a virtual image?

A real image is formed by extending the rays back to where they appear to come from.

A real image is always upright and never inverted.

A virtual image is always smaller than the object.

Light rays actually pass through a real image.

@PsiSquared What do you think? I was thinking that the answer was B.

It's not B.  Real images are generally rotated 180°, but not always.  Light rays do always pass through a real image, so D is the answer.
