The two primary layers' corresponding de-clutter layers are identified by which markers?

The correct answer is associated with the identification of the two primary layers' corresponding de-clutter layers through specific markers. In various operational and navigational systems, markers play a crucial role in differentiating between layers of data being displayed.

The distinction you see in the markers, such as 1D and 2D, typically indicates a specific system of categorization or identification within a piece of equipment or a display interface. In essence, these markers are used to relate the primary layers and their de-clutter counterparts, allowing operators to manage and interpret information effectively under varying conditions.

Understanding these markers is fundamental, as effective situational awareness and information overload management rely on the proper coordination between primary and de-clutter layers. The de-clutter layer serves to simplify the display, making it easier for operators to focus on critical information without being distracted by less important data.

Other options presented do not align with the customary designation system used for these layers and markers, which is why they do not correctly identify the relationship of the de-clutter layers to the primary layers.
