Answer:
B, embargo
Step-by-step explanation:
An embargo can be defined as an official ban on trading or commercial activites on a country by another country or group of countries.
This is mostly as a form of economic punishment for the erring country as a result of it flouting a certain agreement or over security concerns.
A clear and recent example is the laying of embargo by POTUS Donald J. Trump on Iran for its recent behavior.
Cheers.
