The correct answer is: C. text-align-last
The text-align-last property defines the text alignment rules on the alignment of the last line of an element. It can be used to align the last line of text to the left, right, center, or justify it.
The text-justify property is used to justify the text within an element. It can be used to stretch the text to fill the entire width of the element, or to distribute the space between words and letters evenly.
The text-fill-color property is used to specify the color of the text. It can be used to change the color of the text in an element, or to add a background color to the text.
The none of the mentioned option is incorrect because it does not specify a valid CSS property.
