• A. Azotobacter
• B. Azospyrillum
• C. Basillus & Pseudomonas
• D. Cyanobacteria

Answer 1

The correct option is C Basillus & Pseudomonas

A.Azotobacter is a genus of usually motile, oval or spherical bacteria . It has several metabolic capabilities, including atmospheric nitrogen fixation by conversion to ammonia.

B.Azospirillum bacteria can promote plant growth.

C.The bacteria Basillus & Pseudomonas convert non labile Phosphorous through either inorganic Phosphorous solubilizing or organic Phosphorous mineralization processes.

D.Cyanobacteria, also known as Cyanophyta, are a phylum of bacteria that obtain their energy through photosynthesis, and are the only photosynthetic prokaryotes able to produce oxygen.

So the correct option is ' Bacillus & Pseudomonas ' .
