B Correct answer
Explanation

In 40 litres with ratio 5:3, milk = 25 litres, water = 15 litres. When 8 litres is removed (in same ratio 5:3), milk removed = 5 litres, water removed = 3 litres. Remaining: milk = 20 litres, water = 12 litres. After adding 8 litres water: milk = 20 litres, water = 20 litres. New ratio is 1:1. Option B is correct.
