This answer will vary a lot, depending on who you will ask. If you're asking proponents of the LCHF (low carbs, high fat) diet, they would say you should reduce your intake of carbohydrates down to around 10 to 20 percent, making either A or C your desired answer.
If you would ask people who propose the current nutritional guidelines as the best way of eating, the amount of caloric intake that should come from carbs according to them would be more in the range of around 40%, making B the correct answer.
There isn't really any clear cut answer here.
I would say that the most correct statement is the following one:
Certain types of renewable energy can be used for as many applications as certain types of nonrenewable resources.

Answer:
I think that it's A.
Explanation:
It's not D, because A & C contrast each other.
Chloroplasts
Chloroplasts capture the energy in sunlight and use it to synthesize energy-rich carbohydrates. This food made by chloroplasts provides the chemical energy needed by all forms of life. Mitochondria help cells to extract the energy in food molecules efficiently to power cellular activities.
