The correct answer is:

- the boundary between the crust and the mantle

To understand the concept of the Mohorovičić discontinuity, we need to understand that the Earth's interior is composed of several layers, such as the crust, mantle, and core. The Mohorovičić discontinuity (also known as the Moho) specifically refers to the boundary between the crust and the mantle.

To determine the Moho, scientists use seismic waves. Seismic waves are energy waves that are generated by earthquakes or other sources and propagate through the Earth. When seismic waves encounter a boundary between different materials with different densities or properties, they can change their speed and direction. By analyzing the behavior of seismic waves, scientists can detect and study the various layers within the Earth.

In the case of the Moho, the seismic waves undergo a significant change in velocity as they pass from the Earth's crust into the underlying mantle. This change in velocity indicates a boundary between the two layers, which is known as the Mohorovičić discontinuity.

Overall, the Mohorovičić discontinuity is an important geological feature that marks the boundary between the Earth's crust and mantle, and it can be identified by studying the behavior of seismic waves.
