Avolcano with basaltic magma would probably erupt with a violent pyroclastic flow erupt with a gradual lava flow erupt with explosions of tephra not erupt at all, but remain in the magma chamber and cool

The correct answer is - Erupt with a gradual lava flow.

The volcanoes with basaltic magma are known for having no explosive eruptions because of the low gas content of the magma, as well as its low viscosity. These types of volcanoes usually start their eruptions with the so called ''flame fountains'' which are actually burning gasses, and after that, gradually, the magma comes out on the surface, and at that point is classified as lava, and starts to flow down from the volcano as lava flows.
