The sentence says that the “_________ antics” of the group “flouted” (openly ignored or disobeyed) “the conventions of the establishment.” “Brazen” and “insolent” can both mean to openly ignore or disobey and they are the correct answers. “Socialist” and “communist” form a tempting pair because people who adhere to either socialist or communist beliefs might well have disagreed with “the conventions of the establishment” in the United States in the 1960s, but neither term means to disobey. “Anarchist” is perhaps the most tempting wrong answer because anarchists do not believe in formal governments and are sometimes described as agitators or insurgents, but there is no match for “anarchist” among the choices, so it cannot be correct. “Fastidious,” or particularly concerned about detail or cleanliness, most certainly does not describe the behavior of the Yippies.
