D Correct answer
Explanation

The price after the first 15% discount is 530 * 0.85 = 450.5. To find the second discount x, solve 450.5 * (1 - x/100) = 396.44, which gives (1 - x/100) = 0.88, so x = 12.

AI explanation

After the first discount of 15%, the price becomes 530 times 0.85, which equals 450.50. The price is further reduced to 396.44, meaning the second discount amount is 450.50 minus 396.44, or 54.06. The second discount percentage is (54.06 divided by 450.50) times 100, which equals exactly 12. The value of x is 12.
