Final answer:

The hair color formula for achieving level 7 cool tone on grey hair is a mixture of 1 oz 7A (ash), 1 oz 7N (natural), and 2 oz of a 30-volume developer.The correct option is b) 1 oz 7A + 1 oz 7N + 2 oz 30-volume developer.

Explanation:

The 7A in the formula provides the ash base which helps to negate unwanted warmth, delivering a cool tone.

The 7N ensures that the grey coverage is naturalistic and well-blended. A 30-volume developer is typically used to open the hair cuticle enough to deposit the color properly within the grey hair which can be more resistant to color than pigmented hair. The presence of the natural (N) shade in the formula is crucial for providing adequate grey coverage.
