A clean brush creates a new pale ring while lifting colour. What correction is appropriate?

Correct answer: Rinse and blot the brush well and keep it slightly less wet than the surface

The governing concept is moisture balance during lifting. A brush that is too wet can release clean water onto the surrounding paint, pushing pigment outward and leaving a pale ring or tide mark. Option B is correct: rinse away pigment, blot excess water, and keep the brush slightly less wet than the paper. More water or wetter paper increases the risk, while black paint is unrelated.
