Explanation:

- Certain living organisms can affect the appearance and preservation of historical monuments.

- Option 1: Amphibious plants - Typically found in wet environments, not known for affecting monuments.

- Option 2: Lichens - Correct. Lichens, a symbiotic relationship between fungi and algae, can grow on stone surfaces, causing discoloration and surface degradation.

- Option 3: Bacteria - While some bacteria can cause deterioration, lichens are more visibly impactful on appearance.

- Option 4: Viruses - Do not affect monuments as they require living hosts for growth.
