Pyocyanin is characteristically produced by which organism?

Explanation:
Pyocyanin is a blue-green pigment produced by Pseudomonas aeruginosa. This phenazine pigment gives colonies a distinctive blue color and can diffuse into the surrounding agar, which makes P. aeruginosa stand out on pigment-enhanced media. The other organisms listed do not characteristically produce this blue pigment, so the presence of pyocyanin strongly points to Pseudomonas aeruginosa as the organism.
