Quasars—such as J0313-1806, located in the Eridanus constellation—are extremely luminous galactic nuclei powered by supermassive black holes. Quasars range in age, with approximately 200 of them known to have developed within the first billion years of the formation of the universe. Scientific researchers have long wondered how any quasars could have formed so early in the universe's evolution given that conditions are believed to have been ill-suited to their creation, which suggests that       
Which choice most logically completes the text?
J0313-1806 is likely less massive than quasars that formed more than a billion years after the beginnings of the universe.
A
J0313-1806 is thought to have formed less than a billion years after the beginnings of the universe.
B
some aspect of the scientific understanding of quasar formation or the early universe may be incomplete.
C
quasars that formed in the early universe are likely not as luminous as those that formed later.
D
