- A concave lens is a lens that possesses at least one surface that curves inwards.
- It is a diverging lens, meaning that it spreads out light rays that have been refracted through it.
- A concave lens is thinner at its centre than at its edges and produces an erect and diminishing image.

The answer to the question is option 'B' - Concave lens.
Explanation:
A lens is a transparent medium bounded by two curved surfaces. It can be either convex or concave, depending on the shape of the surfaces. The behavior of a lens in terms of image formation depends on the curvature of the surfaces.
Convex Lens:
- A convex lens is thicker in the middle and thinner at the edges.
- It converges the incoming light rays to a point called the focal point.
- When an object is placed beyond the focal point, a real and inverted image is formed on the opposite side of the lens.
- The image formed by a convex lens can be either magnified or diminished, depending on the position of the object.
Concave Lens:
- A concave lens is thinner in the middle and thicker at the edges.
- It diverges the incoming light rays.
- When an object is placed in front of a concave lens, the diverging rays appear to originate from a point called the virtual focal point.
- As a result, a virtual, erect, and diminished image is formed on the same side as the object.
- The image formed by a concave lens is always virtual, erect, and diminished, regardless of the position of the object.
Comparison:
- Convex lenses can form both real and virtual images depending on the position of the object.
- Concave lenses, on the other hand, always form virtual, erect, and diminished images regardless of the object's position.
- Therefore, the correct answer is option 'B' - Concave lens.
