Which of the following retail chains is owned by Hudson's Bay Company?

Designer Depot is the correct answer because it is part of the Hudson's Bay Company (HBC) retail group. HBC is a historical Canadian company that has owned various retail chains over the years. Designer Depot, which focuses on providing discounted designer brand items, aligns with HBC's strategy of offering a range of department stores and off-price retail options.

In contrast, Zellers was a discount retailer that was once owned by HBC but has since closed most of its locations, and its brand has been revitalized as a store format under HBC’s new initiatives. Target is an American retail chain that was not owned by HBC; although it attempted to expand into Canada, it exited the market. Walmart, another well-known retail chain, is an entirely independent entity and operates without any affiliation to HBC. Thus, the ownership by HBC is specifically applicable to Designer Depot among the provided options.
