A. Exporting oil to Israel,
Because, during the 1973 Arab-Israeli War, Arab members of the Organization of Petroleum Exporting Countries (OPEC) imposed an embargo against the United States in retaliation for the U.S. decision to re-supply the Israeli military and to gain leverage in the post-war peace negotiations.
I'm not sure though
The Nullification Convention met in 1832. The convention declared the tariffs of 1828 and 1832 unconstitutional and unenforceable within the state of South Carolina after February 1, 1833. Decision of forcefully collecting taxes caused conflict between South Carolina and the United States.
Explanation:
The Ordinance of Nullification was caused by the belief that the tariffs of 1828 and 1832 favored the North over the South and therefore violated the Constitution. This led to the protest and conflict in between South Carolina and United States.
The imposition of tariffs argued that the U.S. Constitution gave rights to the states to block the enforcement of a federal law. Congress passed the new negotiated tariff to South Carolina. The convention declared the tariffs of 1828 and 1832 unconstitutional and unenforceable within the state of South Carolina after February 1, 1833.
