A)Lava dome with internal pressure✓
B)Extensive, low-viscosity basalt plateau
C)Formation of a deep maar crater
D)Rapid pyroclastic flow occurrence

A lava dome can form when viscous lava is blocked, because pressure builds within the volcano which inflates it via magmatic intrusion, therefore forming a dome, rather than eruptions onto flatter ground.
