Correct answer: A. Interferons
- A. Interferons
- B. Histone

Explanation
Interferons are proteins that play a key role in controlling viral infections. They boost the body's immune defenses and help limit the spread of viruses within the body. The other options listed (antigen, histone, and serum) are not molecules specifically used to control viruses during infection but may have other roles in immune responses or cellular processes.

The major groups include prokaryotes, protists, fungi, plants and animals, with comparisons based on cell type, cell wall, nutrition, body organization, reproduction and evolutionary relationships; prokaryotes lack a membrane-bound nucleus.
