Final answer:
The sentence that is capitalized correctly is: Every January, the Girl Scouts of America sell cookies.
Step-by-step explanation:
The sentence that is capitalized correctly is: Every January, the Girl Scouts of America sell cookies.
In this sentence, the days of the week, months, and proper nouns are capitalized, which follows the standard rules of capitalization in English. For example, January is a month and it is capitalized, while Girl Scouts of America and America are proper nouns and are capitalized as well.
The other options, O Every january, the girl scouts of America sell cookies. and O Every January, the girl scouts of America sell cookies. are incorrect because they do not capitalize the first letter of the month or the proper nouns 'Girl Scouts of America' and 'America'.
