Final answer:
The best way to obtain pale blonde results is typically to use High-lift color. Hence the correct option is A.
Step-by-step explanation:
High-lift color is a type of hair color that is designed to lighten the hair more effectively than traditional permanent hair color. It is often used when aiming for significant lightening, such as achieving pale blonde shades. High-lift color contains more ammonia and a higher concentration of developer (peroxide) than regular hair color.
Demi-permanent color (Option b) and semi-permanent color (Option d) are less effective for achieving significant lightening and are generally used for depositing color or enhancing existing hair color without significant lift. Permanent color (Option c) can provide lightening, but high-lift color is specifically formulated for achieving pale blonde results with minimal damage to the hair.
