Final Answer:
The three kingdoms for lichens are B. Plantae, C. Fungi, and A. Eubacteria.
Step-by-step explanation:
Lichens are unique symbiotic associations between fungi, algae, or cyanobacteria. The primary partner in the lichen symbiosis is a fungus, which forms a mutualistic relationship with a photosynthetic partner (either algae or cyanobacteria). The fungal partner provides a protective environment and absorbs water and nutrients, while the photosynthetic partner produces food through photosynthesis. Therefore, the three kingdoms involved in lichen symbiosis are Fungi (represented by the fungal partner), Plantae (represented by the photosynthetic algae), and Eubacteria (represented by cyanobacteria, which are prokaryotes). Lichens do not involve the Animalia kingdom.
Options B, C, and A are the answer.
