Explanation:

To solve this, we analyze each option:

• Option A: Bacteria are single - celled prokaryotes. Tapeworms are not bacteria.
• Option B: Parasites are organisms that live on or in a host organism and get their nutrients at the host's expense. Tapeworms live in the human body (host) and obtain nutrients from it, so they are parasites.
• Option C: Viruses are non - cellular entities that need a host to replicate. Tapeworms are multicellular organisms, not viruses.
• Option D: Fungi are a separate group of organisms (e.g., yeasts, molds). Tapeworms do not belong to the fungi group.

B. Parasite
