To find the percentage off, we need to calculate the difference between the original price and the price after the coupon is applied, and then divide that difference by the original price.
Original price - Price after coupon = $649 - $519.20 = $129.80
Percentage off = (Difference / Original price) * 100
= ($129.80 / $649) * 100
= 0.20 * 100
= 20%.
Therefore, the coupon is for 20% off. The correct answer is option C.
