Why does fossil fuel use in the united states make the u. s. vulnerable to the political wishes of foreign countries?

a: the us is a net exporter of fossil fuels.
b: fossil fuels lead to global climate change.
c: the us imports much of its petroleum from foreign countries which set the prices.
d: all of the above.

Option A , The US is a net exporter of fossil fuels.

Explanation:

US is a developed nation with the highest consumption rate of fossil fuel or petroleum product per person. Thus, in order to meet out its domestic requirement US has to earlier  import fossil fuels from other countries. But after the discovery of new fossil fuel reserves in year 2016-2017, US has stopped importing fuel but on the other hand has started exporting it due to which the price of crude oil per barrel has fallen to great extent during 2017 to till today.

Hence, US is a vulnerable to the political wishes of foreign countries based on its fossil fuel use
