B Correct answer
Explanation

Let original price = 100. New price = 100 - 42 = 58. To return to 100, increase = 42. % increase = (42 / 58) * 100 = 72.41%.

AI explanation

Assume the original price is 100, making the reduced price 58. To find the required percentage increase to restore the price to 100, use the formula (change / initial value) * 100. The calculation is ((100 - 58) / 58) * 100 = (42 / 58) * 100 = 72.41 percent.
