Solution

The correct option is B
convex

Only convex lenses give enlarged images of objects. Convex lenses can give diminishes, same sized or enlarged image. Concave lenses produce only diminished image. So, if the image of an object in front of a lens is larger than the object, this implies that the lens is convex.
