A. It seems that Americans have a great capacity for consuming popcorn, spending $250 million on the snack in theaters each year.
This is the correctly edited sentence. It uses the correct verb "seems" to mean "appears". The other "seam" refers to where two pieces of something come together like cloth to make a shirt. This also capitalizes the proper noun, Americans, corrects the spelling mistake for theaters, and corrects the slang for year. The difference between A and B is that B has the word "dollars" after million. Since the dollar sign has been added before 250, the word dollars should not be included after million.
