Explanation:

The Mohorovicic discontinuity (the Moho) is the boundary between the Earth's crust and the mantle. It was discovered by seismologist Andrija Mohorovičić. Seismic waves change speed when they cross this boundary, which is the first major seismic discontinuity. The other options (Stephenson, Huckleberry, Ramirez discontinuities) are not recognized in geological or seismological studies.

Answer:

Mohorovicic discontinuity, "the Moho"
