B Correct answer
Explanation

Spirulina is a classic example of Single Cell Protein (SCP) - a protein-rich biomass produced from microorganisms (cyanobacteria in this case) used as food or feed. It contains 60-70% protein and is cultivated for its nutritional value. Agar-agar is a polysaccharide from algae, while Rhizobium, Acetobacter, and Salmonella are bacteria not typically produced or used as SCP sources.
