(A) Transposons move via an RNA intermediate, while retrotransposons move via a DNA intermediate.
(B) Transposons are less prevalent and move via an RNA intermediate, while retrotransposons are more prevalent and move via a DNA intermediate.
(C) Transposons move via a DNA intermediate, while retrotransposons are more prevalent and move via an RNA intermediate.
(D) Both transposons and retrotransposons move via a DNA intermediate, but only retrotransposons create new copies.
