The correct answer is option (d). Algae and fungus.

• The two micro-organisms which live in symbiotic association in lichens are algae and fungus.
• Mutualistic interactions between free-living, autotrophic algae and heterotrophic fungi are widespread in nature.
• A lichen is a composite organism consisting of a fungus (the mycobiont) and a photosynthetic partner (the photobiont) growing together in a symbiotic relationship.
• The dominant partner in a lichen is the fungus.
• The fungi provide a moist, sheltered habitat for the algae, and, in turn, the algae provide food for the fungi.
• Lichens also serve as air quality indicators, as they are mostly seen in areas with pure air.
