A Correct answer
Explanation

In 25 litres, acid is 4×5 = 20 litres and water is 5 litres (since 4:1 ratio means 4 parts acid and 1 part water, total 5 parts). After adding 3 litres water, total water becomes 8 litres while acid remains 20 litres. The new ratio is 20:8 = 5:2 after dividing by 4. Therefore, option A is correct.
