What analogy is presented in the Scotchgard advertisement?

The analogy presented in the Scotchgard advertisement is that Scotchgard protects furniture in a manner similar to how sunscreen protects skin. This comparison emphasizes the concept of safeguarding and prevention; just as sunscreen is a barrier against harmful UV rays that can damage the skin, Scotchgard serves as a protective layer for furniture against dirt, stains, and spills. The effectiveness of sunscreen is widely understood, allowing the analogy to resonate with consumers by illustrating Scotchgard's protective qualities in a familiar context, reinforcing the idea that using Scotchgard is a proactive measure to preserve the integrity and appearance of furniture, much like applying sunscreen is a standard practice for skin health.

While other choices focus on different aspects of Scotchgard's function, none convey the direct protective analogy as effectively as the comparison to sunscreen.
