Pyocyanin pigment is characteristically produced by which organism?

Explanation:
Pyocyanin is a blue-green pigment produced by Pseudomonas aeruginosa. This distinctive pigment colors colonies and is a classic clue in identifying P. aeruginosa, reflecting a redox-active phenazine that also contributes to virulence. The other organisms listed do not characteristically produce this blue pigment; they are known for other pigments or lack a defining blue pyocyanin pigment. So, the best match is Pseudomonas aeruginosa.
