Solution
The correct option is B discontinuity
In
geology the word "discontinuity" is used for a surface at
which seismic waves change velocity. One of these surfaces exists at
an average depth of 8 kilometers beneath the ocean basin and at an
average depth of about 32 kilometers beneath the continents. At this
discontinuity, seismic waves accelerate. This surface is known as the
Mohorovicic Discontinuity or often simply referred to as the "Moho."
