The oceanic crust gets carried underneath another tectonic plate and it sinks hundreds of miles into the Earth's Mantle.
That would be D. Isovolumic contraction
As the name states during ISOvolumic contraction the volume of the ventricles doesn’t change and stays the same so no blood enters or leaves the ventricles. The thing that changes is the pressure of the ventricles that increases.
I can explain the process more if u want in the comments:)
