The correct answer is D. All of the mentioned.

The rotate-Z(), rotate-Z-axis(), and rotateZ() transform property values all define a 3D rotation along the Z-axis.

The rotate-Z() transform property value is a shorthand for rotate-Z-axis(angle). The rotate-Z-axis() transform property value is a more explicit way of specifying a 3D rotation along the Z-axis. The rotateZ() transform property value is a CSS3 property that is equivalent to rotate-Z().

The following code snippet shows how to use the rotate-Z() transform property to rotate an element by 30 degrees around the Z-axis:

div { transform: rotateZ(30deg); }

The following code snippet shows how to use the rotate-Z-axis() transform property to rotate an element by 30 degrees around the Z-axis:

div { transform: rotateZ-axis(30deg); }

The following code snippet shows how to use the rotateZ() CSS3 property to rotate an element by 30 degrees around the Z-axis:

div { -webkit-transform: rotateZ(30deg); -moz-transform: rotateZ(30deg); -o-transform: rotateZ(30deg); transform: rotateZ(30deg); }
