Question $5$: Considering the mobile$-$first design philosophy and the principles of Responsive Web Design $($RWD$),$ what should Anders prioritize when developing JTNorth's website to ensure it provides an optimal experience for mobile visitors while still accommodating desktop visitors?

Developing two separate versions of the website: one optimized for desktop with extensive features and another simplified version for mobile devices

Starting the design process with the mobile user experience in mind, focusing on simplified navigation, fast load times, and touch$-$friendly interfaces, and then scaling up the design for desktop users

Focusing on desktop design with extensive multimedia content and encouraging mobile users to use the desktop mode on their devices to access the full website experience

Designing the website with high$-$resolution images and complex animations to make a strong visual impact.
