Implementing responsive design principles is essential for ensuring a website is mobile-friendly because it allows the website to adapt its layout and content based on the screen size and orientation of the device being used. This approach ensures that users have an optimal viewing experience on a variety of devices, from smartphones to tablets to desktops. Responsive design uses techniques such as fluid grids, flexible images, and media queries to automatically adjust elements on a page so that they are visually appealing and functional, regardless of the device.

In contrast, using larger images may not necessarily make a website more mobile-friendly; it can actually slow down loading times on mobile devices if not handled properly. Choosing vibrant colors can enhance a visual aspect but does not directly contribute to the usability or navigability of a site on mobile devices. Similarly, incorporating videos may add value to the content but doesn't inherently address the layout and user experience issues that responsive design principles do. Thus, the correct approach to achieving a mobile-friendly website centers around the implementation of responsive design.
