The correct option is C golden yellow
A combination of ammonia and hydrogen peroxide is often used in the process of bleaching hair. Hydrogen peroxide has the necessary properties to remove the color from hair.
It oxidizes one of hair's melanin pigments to a colorless substance. This results in the hair becoming lighter. Done time and time again, bleaching can lead to hair becoming a very light golden yellow color.
