Answer:

D. Hot mantle plumes rise toward the surface within a plate

Explanation:

Intraplate volcanism happens inside a plate, not at a plate boundary.

Thus, Options B and C are wrong.

In intraplate volcanism, a hot mantle plume slowly rises by convection from the lower mantle and creates a hot spot at the base of a plate, penetrating the crust and causing localized volcanic activity.

A. is wrong. Descending magma would not cause volcanic activity .
