Question

Quizplus · Accepted Answer

The correct answer is D because Gram-negative bacteria are not characterized by a negative stain. Instead, they are distinguished by their reaction to the Gram stain process, where they do not retain the crystal violet stain and are counterstained pink by safranin. The term "negative stain" is misleading in this context, as it typically refers to a staining technique used to visualize bacteria against a dark background, not the Gram staining reaction of bacteria.
