c. the us imports much of its petroleum from foreign countries which set the prices.
d. all of the above.

The correct answer is (C):

The US imports much of its petroleum from foreign countries which set the prices.

The explanation:

1- United States is is having a high usage of fossil fuels.

2- They don't have the resources for that.

3- So, they import fossil fuel from gulf regions, which is very far from United States.

4- So they depend on the oil in Middle East which makes America vulnerable.

5- and they accept the prices that the gulf provides them. that the high reason makes United States vulnerable.

i think it is true since you can test the answer and can use observations to complete it.
