Which of the following would be most consistent with an origin of Upheaval Dome by rising mama?

A) an igneous body should exist beneath the crater
B) baking of the layers closest to the magma
C) an age determination on igneous rocks that is younger than the age of the rock layers
D) all of these

All of these options are consistent with an origin of Upheaval Dome by rising magma. An igneous body beneath the crater, baking of the layers closest to the magma, and an age determination on igneous rocks that is younger than the surrounding rock layers all support the theory of a magmatic origin.
