Which of the following is a DNA virus with an envelope?

Explanation:
Enveloped DNA viruses are those that have a lipid envelope surrounding the capsid, acquired from the host cell membrane during budding. Among the options, Hepatitis B is the only one that is both a DNA virus and enveloped. It’s a member of the Hepadnaviridae and has a lipid envelope, with a partially double-stranded DNA genome that relies on reverse transcription during replication. The others are not: Adenovirus is a naked (non-enveloped) double-stranded DNA virus; Rhinovirus is an RNA virus that is non-enveloped; Papillomavirus is a naked double-stranded DNA virus. Therefore, Hepatitis B best fits the description.
