All of the following adaptations could lead an organism to be successful
tamaranim1 [39]

Answer:

OB) An elephant in the savannah develops without the ability to hear. A salamander living in a cave is born without, eyesight or fully developed eyes.

Explanation:

Adaptations are gradual modifications and changes in the physical characteristics or behavior of an organism, so that it could facilitate the survival of the organism in that particular environment.

In case of elephant without ability to hear specially in the regions of Savannah where there is vast grasslands with scanty vegetation and animals, then the elephant can't hear any sound of danger like approaching calamities, also it could hear the call of other elephants, in case if the elephant becomes segregated.

In salamander, low eyesight or low vision will further add to the misery, as there is already darkness in the cave. It could fall prey to any predator or it could not be able to feed on consumable organisms as it could see properly.
