Maybe A, B, and D, this could be wrong but my best guesstimate

The correct answer would be: dependence on nonrenewable resources.
A nonrenewable resources are resources that cannot be readily replaced by natural means, such as fossil fuels (oil, natural gas). The use of these resources is not sustainable because their formation takes billions of years. The whole world is dependent on these non-renewable sources but they are becoming more scarce daily.
I believe you are talking about Stem Cells.
