Which of the following is not one of the original 13 colonies?

The correct answer is Florida, as it was not one of the original 13 colonies established by the British in North America. The original colonies were founded along the Atlantic coast from present-day Maine to Georgia, including states like Connecticut, Georgia, and Pennsylvania. Florida, however, was acquired by the United States from Spain in the early 19th century, long after the original 13 colonies were established and declared independence from British rule. This distinction is fundamental in understanding the early colonial history of the United States and the geographic and political development of the nation.
