C Correct answer
Explanation

Initial: 80L, ratio 5:3 -> 50L milk, 30L water. Remove 16L mixture: 16 * 5/8 = 10L milk removed, 16 * 3/8 = 6L water removed. Remaining: 40L milk, 24L water. Add 16L milk: 40+16 = 56L milk, 24L water. Ratio 56:24 = 7:3.

AI explanation

In the initial 80 L mixture, the 5:3 ratio gives 50 L of milk and 30 L of water. Removing 16 L of the mixture removes 10 L of milk and 6 L of water, leaving 40 L of milk and 24 L of water. Adding 16 L of milk brings the totals to 56 L of milk and 24 L of water, which simplifies to a 7:3 ratio.
