Both Assertion and Reason are incorrect.

(D) Teminism,also known as reverse transcription,refers to the synthesis of $DNA$ from an $RNA$ template. This process is catalyzed by the enzyme reverse transcriptase ($RNA$-dependent $DNA$ polymerase),not $DNA$-dependent $RNA$ polymerase.Since Teminism involves the flow of information from $RNA$ to $DNA$,it contradicts the central dogma's concept of unidirectional flow $(DNA \rightarrow RNA \rightarrow Protein)$.Therefore,the Assertion is incorrect because Teminism represents a deviation from the standard unidirectional flow,and the Reason is incorrect because it cites the wrong enzyme.
