Answer 2

Answer:

Virtual and erect.

Step-by-step explanation:

Since, the power of lens is negative, it shows that the focal length of the lens is also negative. And we know that the focal length of a lens would be negative only if the lens is concave lens. And in any position of the object in concave lens, the nature of image is always 'virtual and erect'.
