Answer:
The options

B) retroviruses that require a DNA intermediate
C) single-stranded DNA viruses such as herpesviruses
D) nonenveloped double-stranded RNA viruses
E) linear double-stranded DNA viruses such as adenovirus
The correct answer is B.
B) retroviruses that require a DNA intermediate
Explanation:
Since the baltimore's scheme which was used for virus classifications was included, the most closely likely alternative of virus to the given polio virus that possess a single stranded RNA in these case study is more likely to be retroviruses that needs a DNA intermediate.
Unlike the single-stranded RNA viruses, the retroviruses lack DNA but possess the enzyme called reverse transcriptase used for RNA replication into the host cells DNA and take advantage of the end product for their favour.
I hope this answer helps.
