The correct answer is C. text-overflow.
The CSS property text-overflow determines how overflowed content that is not displayed is signaled to the users. It can be used to clip the overflow, hide it with an ellipsis, or display a custom string.
The text-flow property is used to control the direction of text flow. It can be used to set the direction to left-to-right, right-to-left, or top-to-bottom.
The text-underflow property is not a valid CSS property.
Here is an example of how the text-overflow property can be used:
css
p {
text-overflow: ellipsis;
}
This will cause the text to be clipped if it overflows the width of the container, and an ellipsis will be displayed to indicate that there is more text that is not being displayed.
