The biological name of Indian Bdellium is Commiphora wightii. It is a plant species from the Commiphora genus, and it is used in traditional medicine for its anti-inflammatory and antimicrobial properties.
All four options are species within the same genus, Commiphora, so the question is really asking which particular species is the source of Indian Bdellium, also called guggul.
Since the resin marketed as Indian Bdellium is obtained specifically from the guggul shrub, whose current accepted name is Commiphora wightii, the correct answer is Commiphora wightii.
