By
definition pedantic means ’a person who bothers people by making unintelligent
comments onto things or the one who show off knowledge to much. Among the
choices the best answer would be letter A: scholarly. It means that the
knowledge shared is something well-searched, peer-reviewed or has concrete
backup findings. Childish is of course, a premature understanding of things
dealing with emotions alone. Ignorance is a bliss. And sophisticated is using
reasonable arguments or rather ‘sound arguments’ that basically feels right but
are actually wrong.
