What is the difference between a quattro and an S line on an Audi?

I am looking to buy an Audi and I am unsure about the differences between the quattro and S line options. Can someone explain?

The quattro option on Audi vehicles refers to the all-wheel drive system, which provides better traction and handling in difficult road conditions. The S line, on the other hand, is an exterior appearance package that adds sportier design elements to the car.

Quattro is a must-have for those living in snowy or rainy areas, as it greatly helps with stability and control. The S line package is more for those who want a visual upgrade on their Audi.
