Answer:<u> Option D
</u>
Solar panels contain a very expensive element, i.e. silicon. This element is able to convert the solar energy into electric energy. The cost of the solar panel gets expensive because of this rare element. It is found in limited areas of the world. That’s why option D is correct. Coal is not used in solar panel, so option B is incorrect. Neither is wind energy, so option A is also incorrect. Water is also not used for exploiting solar energy, which makes option C a wrong answer.
They may either release heat or gain heat. With a temperature increase, the kinetic energy increases and the state of matter will increase (example, ice to water aka solid to liquid)
If the temperature decreases, then the kinetic energy decreases and the state of matter will decrease (example, water vapor to water aka gas to liquid)
Have a nice day!
I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

There are three sources of genetic variation: mutation, gene flow, and sexual reproduction. A mutation is simply a change in the DNA.
From my speculation it is loss of habitat and global warming
