Quizplus · Accepted Answer

The igneous feature shown in the photograph is a volcanic neck, which is a column of solidified lava that formed in the vent of a volcano. This feature is characterized by its narrow shape and steep sides, and is typically formed from the solidification of magma that has intruded into a vent or fissure of a volcano. A dike is a similar feature but is formed when magma intrudes into a crack in the surrounding rock, whereas a sill is formed when magma intrudes between layers of preexisting rock. A batholith is a large, dome-shaped mass of intrusive igneous rock. None of these other features are consistent with the photograph provided.
