What is the juxtaposition of the rose bush and the prison door an example of?

Visual irony.

A (symbolic logic) and E (Freudian transference) are not literary terms. While B (allegorical archetype) is a literary term, there is nothing archetypal about the rosebush. D (allegorical archetype) is a mere repetition of the question. Thus, C (visual irony) is the correct answer.
