If could be B or also C still kinda confused with the question but if I’m wrong then I’m sorry :(
The answer is B because it comes in 3 stages in which your body reacts
One is fat soluble vitamins!
When you eat foods that contain fat-soluble vitamins, the vitamins are stored in the fat tissues in your body and in your liver. They wait around in your body fat until your body needs them.
The other is water soluble vitamins!
When you eat foods that have water-soluble vitamins, the vitamins don't get stored as much in your body. Instead, they travel through your bloodstream. Whatever doesn't go through your blood stream comes out as urine.
Good luck love!
Answer: In the the next generation I think that climate change will be an even bigger issue,population growth is also a rising issue that is only getting worse, as well as terrorism and maybe some non renewable resources will run out causing us to have to go to more cleaner energy like solar and wind.
