Which innovation helps with customer interaction in communications?

The choice of e-books via Kindle as an innovation that aids in customer interaction in communications is accurate because e-books revolutionize how readers engage with texts and authors. They enable personalized reading experiences through features like note-taking, highlighting, and the ability to interact with authors through social media or online platforms. Readers can instantly connect with communities, access additional content, and receive updates from publishers or authors, enhancing the overall interaction and engagement with the material.

In contrast, the other options—debit cards, interactive assignments, and automatic garbage trucks—do not directly facilitate communication with customers in the same way. Debit cards primarily serve as a payment method without fostering interaction. Interactive assignments may enhance learning but don't focus on customer communication as their primary goal, and automatic garbage trucks improve waste management efficiency but lack a focus on engaging customers in interactions.
