Answer:
B, C, D
Explanation:
In-text citations come after quoted information, so B is a correct answer, thus A is not a correct answer.
C is correct because in-text citations are indeed enclosed by parentheses
D is correct because in-text citations usually only list the author/source and the page number (if there is any). It's much more brief than a full citation (which is usually written at the end of an essay, article, etc). Because of this logic, E is not a correct answer as well (since not all information about a source is given in in-text citations).
F is incorrect for the same reason as E: in-text citations do not list the complete information of a source like a works-cited list does.
