What example illustrates positioning by product attributes and benefits?

The choice that illustrates positioning by product attributes and benefits is exemplified by highlighting how the Apple brand emphasizes the ease of use of its products. This approach focuses on specific characteristics—such as user-friendly design and intuitive interfaces—that provide meaningful benefits to consumers. By positioning itself this way, Apple communicates a clear value proposition that appeals to users who prioritize ease of use in their technology products, effectively differentiating itself from competitors.

The other options do demonstrate successful brand positioning but in different capacities. For instance, while Samsung being a leader in sales points to its market success, it doesn't delve into specific product attributes or benefits. Similarly, Toyota's emphasis on reliability and Nike's focus on high-performance shoes present strong brand messages, yet they lean more toward overall brand reputation and performance rather than strictly defining positioning through distinct attributes and consumer benefits. In contrast, Apple directly addresses how its product features result in advantages for the user, which is the essence of positioning by product attributes and benefits.
