names of school subjects in general (math, science, physical education) are NOT capitalized. these are common nouns and are not necessarily specific to a certain region or school.
names of COURSES, however--these are capitalized. "Algebra II" is capitalized because it references a specific algebra course, though algebra itself, as a school topic, is a common noun. if it names a course, you capitalize it.
"American History" and "Algebra II" will be capitalized because they name courses (history and algebra, but more specific). "French" is capitalized because it is the name of a language, referencing France as a country. this makes it a proper noun.
"chemistry" is not capitalized. this school subject is non-specific--it doesn't name a certain course, like Chemistry 101 or AP Chemistry. it's simply chemistry as a subject, chemistry as a class often taught at many schools. your correct answer is A.
