Answer: a. set the display property of the element within each li element to inline

Explanation: In an unordered list, ul signifies the list and li signifies the elements in the list. When you want to display the elements in a list in a horizontal form, for example if you need a horizontal menu, a quick way of doing this is setting the display of li to inline by writing it as follows in css:

li {

Display: inline;

}

This will order the elements in the list into the form of a horizontal menu.
