Which of the following statements about Texas's entry into the US is accurate?

Texas's entry into the United States is accurately described by the statement that it was the only state to enter by way of a treaty. When Texas declared independence from Mexico in 1836, it became an independent republic. In 1845, Texas was annexed by the United States through a treaty, which was a unique circumstance since most states joined through legislation rather than formal treaties.

The annexation was significant not only due to the treaty process but also because it involved negotiations that addressed borders and other critical issues. This treaty process reflects Texas's unique history and its status as a former independent republic at the time of joining the Union. This historical context sets Texas apart from other states regarding its entry into the United States, reinforcing that it was indeed the only state to achieve statehood through a treaty.
