Which of the following property of a anchor element signifies unvisited hyperlinks?

The correct answer is A. link.

The link property of an anchor element signifies unvisited hyperlinks. It is a CSS property that specifies the color of unvisited hyperlinks. The value of the link property can be a color name, a hex code, or an RGB value.

The visited property specifies the color of visited hyperlinks. The hover property specifies the color of hyperlinks when the mouse cursor is over them. The active property specifies the color of hyperlinks when they are clicked.

Here is an example of how to use the link property:

“`css
a {
color: blue;
}

a:link {
color: red;
}

a:visited {
color: green;
}

a:hover {
color: yellow;
}

a:active {
color: black;
}
“`

This code will make all unvisited hyperlinks red, all visited hyperlinks green, all hyperlinks that the mouse cursor is over yellow, and all active hyperlinks black.
