The answer is ; GRAM POSITIVE / PURPLE

Gram-positive bacteria have a cell wall mainly composed of peptidoglycan layer and teichoic acid embedded within the peptidoglycan layers. This is why the gram-positive bacteria are able to retain the gram stain and remain purple even after washing with alcohol.
