The correct answer is: B. BackgroundColor
The BackgroundColor property is a CSS property that sets the background color of an element. It can be used to set the background color of any element, including the body, div, span, and other elements.
The BackgroundColor property takes a color value as its value. The color value can be a hex code, a color name, or an RGB value.
For example, the following code sets the background color of the body element to red:
body {
backgroundColor: red;
}
The following code sets the background color of the div element to green:
div {
backgroundColor: green;
}
The following code sets the background color of the span element to blue:
span {
backgroundColor: blue;
}
The BackgroundColor property is a very useful property that can be used to add color and style to web pages.
The other options are incorrect because they are not valid CSS properties.
