Answer:
C. OPEC nations stopped p shipments to the united states.
Step-by-step explanation:
This was was said to take place in the early 1970s, consumption of oil by Americans in the form of gasoline and other products was rising even as domestic oil production was declining, leading to an increasing dependence on oil imported from abroad. Despite this, Americans worried little about a dwindling supply or a spike in prices, and were encouraged in this attitude by policymakers in Washington, who believed that Arab oil exporters couldn’t afford to lose the revenue from the US market. These assumptions were demolished in 1973, when an oil embargo imposed by members of the Organization of Arab Petroleum Exporting Countries (OAPEC) led to fuel shortages and sky high prices throughout much of the decade.
