Which explanation best accounts for the mineral and structural features observed in this sample?
A
The crystal structure suggests growth under stable pressure conditions that disrupted the alignment of mineral grains.B
The uneven crystal distribution indicates rapid magma ascent, where heat loss prevented uniform crystallization across the rock.C
The rock likely formed at the surface during explosive lava cooling, producing vesicles and trapping volcanic gases.D
The rock likely formed in a deep setting, where unusual chemical conditions enabled selective crystal growth within a finer matrix.
