You want your images to fill the element 100%, but want it to scale for responsiveness (no minimum width). So, in this case, you need to select your images, then tell the browser to max it at 100% (100% of the element they are in). So your code, as well as the quiz response, would be:

img {
  max-width: 100%;
}
