Answer:
A. Yom-Kippur War
Explanation:
The Yom-Kippur War was a conflict mainly pitting Egypt and Syria against Israel. The US was an ally of Israel, so it provided aid in the form of weapons, cargo, and other supplies.
Unfortunately, many of the Arabian countries disliked this and, angered, imposed an embargo on oil shipments to the US, hoping to stop the US from helping.
