B Correct answer
Explanation

Ratio of yellow to red is 3:2. If red = 4 litres, then 2 parts = 4 litres, so 1 part = 2 litres. Yellow = 3 parts = 3 * 2 = 6 litres.

AI explanation

Using the given ratio of yellow to red colour, the proportion is 3 : 2. Let the unknown amount of yellow colour be x litres, setting up the equation 3 / 2 = x / 4. Solving for x gives 2x = 12, so the required amount of yellow colour is 6 litres.
