D Correct answer
Explanation

Let CP = 100. Marked Price = 130. Discount = 10% of 130 = 13. Selling Price = 130 - 13 = 117. Gain = 117 - 100 = 17%.

AI explanation

Assume the cost price is 100, so the marked price at 30% above the cost price is 130. After a 10% discount, the selling price becomes 130 - (10/100 * 130) = 117. Since the cost price was assumed to be 100, the gain percent is 17%.
