B
Spirulina

C
Nostoc

D
Oscillatoria

Solution

The correct option is B Spirulina
Spirulina is, in some ways, similar to bacteria that create Vitamin $$B12$$ in the soil, though it's actually an evolutionary branch-off. The same formation of Vitamin $$B12$$ can take place in spirulina as a Vitamin $$B12$$ (culture) laboratory vat. 

So, the correct option is 'Spirulina'.
