Which CSS property is responsible for changing the text color?

The property that controls the text color in CSS is the "color" property. When you apply this property to an element, it sets the color of the text within that element. For instance, using "color: red;" will change the font color of the text to red. This is the standard syntax recognized by all web browsers and is widely used in CSS styling.

The other choices do not exist as proper CSS properties. "font-color" and "text-color" are not valid CSS properties; instead, developers should always use "color" for text color. Similarly, "foreground" is not a recognized CSS property related to text styling, making it an incorrect choice. Understanding the correct terminology and syntax is essential for effective CSS coding.
