Final answer:
Option (b), To promote the Sauber washer-dryer combo effectively, it is recommended to focus on its cleaning power and convenience.
Step-by-step explanation:
When promoting the Sauber washer-dryer combo, considering what is known about its features and the consumer laundry detergent market, it would be pertinent to highlight attributes that stand out to the target market. In this scenario, focusing on cleaning power and convenience would likely be the most effective strategy. Cleaning power relates directly to the effectiveness of the product in performing its primary task, which is cleaning clothes.
This can be strongly influenced by the presence of surfactants in laundry detergent, as surfactants are crucial for the absorption and emulsification of soil, thus improving the overall cleaning performance. Convenience may include factors such as ease of use, time-saving features, or additional functions that simplify the laundry process for the consumer.
Considering the physical aspects of a product as part of its promotion also includes highlighting the practical benefits or innovative features the product may offer, like a nonstick surface or being newly redesigned for user comfort. This also ties in with convenience, demonstrating an understanding that consumers value not only the functional performance but also the ease and enjoyment of using the product. Therefore, by promoting the washer-dryer's cleaning power and making the laundry process more convenient, marketers can address both the efficiency and user experience, likely resonating with the needs and desires of potential customers.
