In technical drawing, particularly in orthographic projection, the top view provides a comprehensive representation of the object from a horizontal perspective. The critical aspect of the top view is that it effectively illustrates the width and depth of the object, which are two out of the three dimensions of any three-dimensional object.

When observing the top view, height cannot be accurately depicted because the view is from above, essentially flattening the vertical aspect. Therefore, the dimensions that are visible are primarily the width (spanning left to right) and depth (extending toward the back of the drawing), providing crucial details that enable the viewer to understand the object's footprint and spatial extent.

The other response options suggest combinations of dimensions that do not accurately reflect the characteristics depicted in the top view. The statement that the top view includes height is particularly misleading, as it cannot convey the object's vertical measurement from this viewpoint. Hence, the conclusion is that the top view is best associated with displaying width and depth, making the first statement the apt choice.
