Final answer:
Option 2 restates the thesis by explaining that special characteristics help deep-sea creatures survive by navigating their environments, escaping predators, and capturing food, encompassing the key points about deep-sea adaptations.
Step-by-step explanation:
The restatement of the thesis that most accurately encompasses the breadth of deep-sea adaptations is the second option: These special characteristics that allow the survival of deep-sea creatures in the difficult circumstances of the ocean are traits that help them navigate their environments, escape predators, and capture food. This choice captures the essential points that adaptations are necessary for survival in extreme conditions by aiding in navigation, predator evasion, and food acquisition. These deep-sea adaptations can include a range of physical and behavioral characteristics, such as the ability to withstand high pressure and cold temperatures, bioluminescence, and specialized feeding mechanisms, that all serve to enhance the survival and reproductive potential of these species in their specific ecological niches.
