Final answer:
The Frequently Asked Questions (FAQ) link on a cable operator's homepage is the key feature that helps customers find solutions to their problems, offering answers to common questions and allowing self-service support.
Step-by-step explanation:
Among the functions available on a cable operator's homepage to assist customers in finding solutions for their inquiries, the link that stands out is the Frequently Asked Questions (FAQ) link. This link typically leads to a section where common questions are answered, helping customers troubleshoot issues, understand billing, and navigate services without the need to contact customer support directly. Whereas other options such as the internet options tab, the online bill pay link, and the Favorites tab serve different purposes not directly related to issue resolution. The FAQ section is an essential tool for self-service customer support and can address various concerns, including on-demand programming, subscriptions, and even network-specific inquiries.
