(B) Virtual, erect and diminished
A concave lens always produces a virtual, erect and diminished image, irrespective of the position of the object.
Table 9.5 (Chapter 9) explicitly states that for all object positions, a concave lens gives a virtual and erect image that is diminished. The textbook concludes: "A concave lens will always give a virtual, erect and diminished image, irrespective of the position of the object." Remember: concave lens = diverging lens → rays never actually meet → no real image possible.
