Quizplus · Accepted Answer

Herbig-Haro objects are formed when jets of gas ejected by young stars collide with the surrounding interstellar medium, creating shock waves that heat and ionize the gas. This process is characteristic of protostars, which are still in the process of forming into fully-fledged stars. The alignment of the Herbig-Haro objects along two perpendicular lines suggests the presence of a protostar at the center of the obscured region, which is likely driving the jets responsible for creating the objects. Therefore, the best choice is C, a protostar. The other choices, supermassive black holes or pairs of black holes, are unlikely to be associated with the formation of Herbig-Haro objects.
