The correct answer is option 2 - a telescope.

To understand why option 2 is correct, we need to know what the focal length of the objective and the focal length of the eyepiece refer to. In both microscopes and telescopes, there are two lenses involved - the objective lens and the eyepiece lens.

The objective lens is responsible for gathering and focusing light from the object being observed. It has a specific focal length, which determines how far away the lens needs to be from the object to create a clear image.

The eyepiece lens, on the other hand, is responsible for magnifying the image created by the objective lens and bringing it closer to the viewer`s eye. It also has a specific focal length, which determines the distance at which the viewer`s eye needs to be from the lens to see the magnified image clearly.

Now, when the focal length of the objective is greater than the focal length of the eyepiece, it means that the objective lens has a greater ability to gather and focus light compared to the eyepiece lens. This is the case in a telescope, and it allows for objects in the distance to be viewed with greater magnification.

So, in summary, the correct answer is
