Which concept describes a website optimized for use on mobile devices?

• A. Online Catalogs
• B. Event Calendars
• C. Mobile-Friendly Design
• D. Regular Newsletters

Answer: (C)

A mobile-friendly design means the site adapts to smaller screens so users can read and navigate easily on phones and tablets. This approach makes text readable without zooming, ensures buttons and links are easy to tap, and rearranges content so everything stays usable when the screen size changes. It directly addresses how people access sites from mobile devices, which is why it’s the best description for a website optimized for mobile use. The other options describe features like a catalog of items, a calendar of events, or newsletter email content—things that don’t specifically capture how the site works on mobile devices.
