B Correct answer
Explanation

Let salaries be A, B, C. A+B+C = 72000. Savings: A saves 20%, B saves 15%, C saves 25%. Given savings ratio 8:9:20, let savings be 8x, 9x, 20x. Then A = 8x/0.2 = 40x, B = 9x/0.15 = 60x, C = 20x/0.25 = 80x. Sum: 40x+60x+80x = 180x = 72000, x = 400. A's salary = 40x = Rs. 16000.
