Which is a characteristic of the image formed between f and the center of the lens?
the image is located between f and the center of the lens, on the other side of the lens.
the image is real.
the image is upright.
the image is bigger than the actual object.

The image is upright.

Explanation:

A concave lens or diverging lens is thinner at its center and thicker at the edges. The light rays after refraction through the lens appear to diverge from the focus of the lens. A concave lens always forms a virtual image which is upright and diminished.

Thus, the image of the object kept between F and center of the lens would be upright, virtual, diminished and formed at the same side of the object between the focus F and center of the lens.
