C Correct answer
Explanation

If 20% of the spirit is removed, 20% of 80 liters is 16 liters. Thus, y = 16. Since Quantity A is 16 and Quantity B is 16, they are equal.

AI explanation

The problem states that replacing y litres of spirit with water causes a 20 percent decrease in the amount of spirit. Since the container originally holds 80 litres of pure spirit, the amount replaced is calculated as 20 percent of 80. This calculation gives y = 16, which makes Quantity A and Quantity B equal.
