Respuesta :
b mechanical because were not robots and stuff like that
The right option is option B. Mechanical
We already know some organisms that survive through heat, chemical, and nuclear, using its energy to help in its survival at the wilderness. These organisms are called extremophiles. These organisms can survive through extreme conditions, using any way they have as a way of energy or as a way of getting energy from somewhere else.
A good example for that are the tardigrades, this one survived in space for about 11 days in extreme cold conditions and even vacuum, it only used chemical and heat energy to survive this journey, but they made it through. Option B is can't be the right one because if a living being is using mechanical energy to survive, well, it's not actually mechanic, this energy needs to be transformed into another way of power source for its body to retain it.
