One of the decisions that led to conflict between the israelis and palestinian arabs was a resolution passed by the which created two individual states within palestine.
a. united kingdom
b. united states
c. united nations
d. united arab emirates

A) United Kingdom

Explanation:

Under the Balfour declaration from the United Kingdom, and approved by the United Nations, was supported, and technically agreed on a territory partition Between Israel and Palestine. the measure was taken between other reasons,  for the lack of an official territory for the Jew people, forced to spread across Europe and other territories forming different communities.

Is not a secret to affirm that UK made this in order to ¨make a favor¨ to the jews, and receive their support as a strategical ally in WWI times.

However, this ¨territory partition¨  and land assignment for the jew people was a boiling point for a series of political and Belic conflicts between the cultures and religions generating a constant confrontation between factions, leaving thousands of victims in the process.

the doctrine of nullification recommended that states living inside the union have the one-sided, inalienable ideal to void any law made by the national government that could be esteemed illegal.

the united states was shaped based on a general agreement among its individual states. hence, it is inferred that under the hypothesis of invalidation, since the states are the establishment of the union, they have the ability to referee and disprove unlawful laws.
