D Correct answer
Explanation

In 160L mixture, milk:water = 27:5 means total 32 parts. Milk = (27/32) × 160 = 135L and water = 25L. To achieve 3:1 ratio (milk:water), we need 135/(25+x) = 3/1, where x is added water. Solving: 135 = 75 + 3x gives x = 20L. Option C (12L) would give ratio 135:37 which is not 3:1.
