The correct answer is A .
The CPCM course states that promotion is not only a short-term sales tactic; it is also “an important point of differentiation for retailers.” That wording matters. Differentiation is a longer-term strategic goal because it helps the retailer build a distinct market position, image, and brand identity over time.
Retailer image/brand building is therefore the long-term promotional objective. Promotions can train shoppers to associate a retailer with value, convenience, quality, freshness, excitement, seasonal relevance, or category leadership. That is strategic brand building, not just a one-week sales event.
Option B, lobby displays, is a tactical execution vehicle. Option C, weekly advertisement, is a promotional communication method. Option D, online discounts, is a short-term price or digital promotional tactic. These can support the strategy, but they are not the long-term promotional objective itself.
