Hi, the answer would be A - literary criticism. B isn't correct because it doesn't usually apply to literature, but real world. C - why would you need to have the knowledge of the Bible in order to be a literary critic, it doesn't make sense. And D - you use a dictionary to look words up, not to learn how to be a critic.
So A is the only possible solution, because "literary" means it is about literature, and "criticism" is obvious.
