(B) When an object is placed at $2F_1$ (twice the focal length) in front of a convex lens,the light rays originating from the object pass through the lens and converge at $2F_2$ on the other side. The image formed is real,inverted,and of the same size as the object. Therefore,the correct option is $(b)$.
