B Correct answer
Explanation

When selling two items at the same price with equal percentage gain and loss, the overall result is always a loss of (x^2)/100 percent. Here, (20^2)/100 = 400/100 = 4% loss.

AI explanation

When two items are sold at the same price and one has a loss of x percent while the other has a gain of x percent, the net result is always a loss of (x squared) / 100 percent. Here x is 20, so the loss is (20 * 20) / 100. The entire transaction results in a 4 percent loss.
