Which of the following property adds padding to the top of an element?

The correct answer is D. padding-top.

The padding property is used to add space around an element’s content. The padding-top property is used to add space between the top edge of an element and its content.

The height property is used to set the height of an element.

The padding-height property is not a valid CSS property.

The top property is used to set the top position of an element.

Here is an example of how to use the padding-top property:

css
div {
padding-top: 10px;
}

This will add a 10px space between the top edge of the div element and its content.
