tree are put in solution of NaOH and Na2 to remove……….
a) color
b) salt

Explanation: Eumelanin is the pigment primarily responsible for brown, black, and dark red hair colors. Phaeomelanin contributes to yellow and red hues, more common in red and blonde hair. Neuromelanin is found in the brain, not in hair, and is not related to hair color. Therefore, “all of these” is incorrect. ✅ Correct option: 2) Eumelanin
