The correct answer is Option (4) → lucky draw

Option (1) usable benefit — Incorrect. A usable benefit gives every buyer a benefit once he buys above a set amount, such as a holiday package or a discount voucher. Here the prize goes only to coupons picked later, so it is not a usable benefit.

Option (2) refunds — Incorrect. A refund pays back a part of the price on some proof of purchase, such as returning empty wrappers. Here no part of the price is paid back, so it is not a refund.

Option (3) quantity gift — Incorrect. A quantity gift gives extra quantity of the same product to every buyer. Here no extra petrol comes with each purchase, so it is not a quantity gift.

Option (4) lucky draw — Correct. Each buyer gets a coupon, but only the coupons picked in a draw win the prize. A lucky draw coupon for free petrol on buying a certain quantity of petrol is the very example of a lucky draw.
