Mohorovičić's observation, known as the Mohorovičić discontinuity or "Moho," relates to how seismic waves behave as they pass through different layers of the Earth. The correct answer is:
**d. seismic waves travelled at varying speeds**
He observed that seismic waves travel at different speeds depending on the material they are passing through, indicating a boundary between the Earth's crust and the underlying mantle.
