Hi, there. I need a clarification of question number 1, which choice is the best answer?

Something that is perceived as a luxury rather than a need is something that brings pleasure. Worldwide, the majority of people view food, shelter, and water as requirements. Undoubtedly, indoor plumbing and electricity would be included on the list by many Americans. As opposed to being a luxury, internet connection is increasingly considered as a need. But is it actually essential for surviving? What then happens to those who don't utilize or have access to the internet? Could the expansion of e-commerce be impacted by how people view Internet connection as a need or a luxury?
