• C. bacteriophage
• D. naked

Answer: (B)

Verified step by step guidance

1. Understand the concept of viral budding: Budding is a process by which certain viruses exit the host cell by acquiring a portion of the host's membrane, forming an envelope around the virus particle.
2. Identify the types of viruses based on their structure: Viruses can be broadly categorized as enveloped or naked (non-enveloped) based on whether they have a lipid membrane surrounding their capsid.
3. Recall that enveloped viruses acquire their envelope through budding from the host cell membrane, which allows them to exit without immediately lysing the host cell.
4. Recognize that naked viruses typically exit the host cell by lysis, not by budding, because they lack the lipid envelope that can be derived from the host membrane.
5. Conclude that the type of viruses released by budding are enveloped viruses, as this process involves the virus acquiring an envelope from the host cell membrane.
