With which early American colony is William Bradford most closely connected?

Explanation

William Bradford was a key leader and governor of Plymouth Colony, making option A the correct answer. While the Mayflower Compact (option B) was an important document signed by the Pilgrims, Bradford is primarily linked to Plymouth. Massachusetts Bay Colony (option C) and Rhode Island (option D) were separate settlements, and Jamestown (option E) was an earlier English colony unrelated to Bradford.
