The correct answer is option 2, which states that statement 2 only is correct. Let`s dissect each option for a better understanding.

Option 1 states that the American Revolution was a conflict between British settlers and Native Americans. This statement is incorrect because the American Revolution was actually a conflict between the American colonies and Great Britain. The Native Americans played a role in the conflict, but the main participants were the American colonists seeking independence from British rule.

Option 2 states that the Americans refused to pay taxes imposed by the British Parliament in which the Americans had no representation. This statement is correct. One of the major grievances of the American colonists was taxation without representation. They believed that they should have a voice in the British Parliament if they were to be subjected to taxes. This led to protests, boycotts, and eventually to the American Revolution.

Option 3 states that both statements 1 and 2 are correct. However, as explained earlier, statement 1 is incorrect. Therefore, option 3 is not the correct answer.

Option 4 states that neither statement 1 nor 2 is correct. However, as explained earlier, statement 2 is correct. Therefore, option 4 is not the correct answer.

In conclusion, option 2 is the correct
