Answer is Wrong!
The correct answer is: B. outline-color
The outline-color property specifies the color of an outline. It is a CSS property that is used to specify the color of the outline of an element. The outline is a line that is drawn around an element to indicate its boundaries. The outline-color property can be used to change the color of the outline, or to remove the outline altogether.
The color-outline and outline-style-color properties are not valid CSS properties.
