The correct answer is A) Colonies were granted their independence

Explanation:

Throughout the 20th Century, numerous new nation-states were formed. These were mostly colonies of Western powers, which had been fighting for Independence and self-rule.

One of the oldest examples of a nation-state being formed out of Independence from colonial rule is the United States. The United States were a collection of 13 colonies owned by Great Britain.

Some of the recent examples are that of Pakistan and India who were also granted freedom by Great Britain. Another example is that of Saudi Arabia, which became a nation-state after Ottomans lost control over the region.

one of the main reasons was definitely slavery. back in 1861, republican abraham lincoln was elected and ended up being a major influence in the slavery business. slavery greatly affected the texas economy because back in 1845 during the annexation of texas, slaves became a big part of the texas population. many texans that were in favor of the secession influenced groups through party ties.
