Answer: visitors to Lucky Brand who have also visited a competing brand
Explanation:
Remarketing us an online targeted advertising whereby customers are targeted based on the previous internet behaviour that they had. It's done in order for a company to be able to connect with the people who have interacted previously with the company's website.
Remarketing can be used to target everyone that has visited any page on Lucky Brand's website, people who visited only Lucky Brand's homepage and the visitors to the Lucky Brand site who did not make a purchase.
It should be noted that it can't be used to target visitors to Lucky Brand who have also visited a competing brand.
