The correct option is C I, III, IV
A biofertilizer is a substance which contains living microorganisms which, when applied to seed, plant surfaces, or soil, colonizes the rhizosphere or the interior of the plant and promotes growth by increasing the supply or availability of primary nutrients to the host plant.
Cyanobacteria (blue green algae), symbiotic bacteria (Rhizobium, Anabaena) and free living bacteria (Azotobacter, Clostridium) are used as biofertilizers.
Yeast is a microscopic fungus which consists of single oval cells that reproduce by budding, and are capable of converting sugar into alcohol and carbon dioxide.
