The correct answer is reduction in tooth size.
The anatomy of the foot and pelvis are the feature of Australopithecus afarensis that is used to definitively classify this species as a hominin.
<h3>Australopithecines</h3>
Australopithecines are an adaptive radiation of early hominins, all of which were to some extent bipedal, had brains that were only slightly larger than those of apes, and had adaptations to a diet that included at least occasionally hard-to-chew items. They have been identified through research on perhaps ten species that lived in central, eastern, and southern Africa between 4.2 million and 1.0 million years ago. Understanding australopithecines is essential to comprehending not only the diversity of early hominins but also the origins of Homo. Our genus Homo probably originated from this radiation, albeit we are unsure from which species.

The order in which toxic nitrogen compounds are converted to less toxic nitrogen compounds in the nitrogen cycle is NH3 ----> NO2- -----> NO3-
The nitrogen cycle refers to the movement of nitrogen in the ecosystem. The process of converting nitrogen into less toxic forms of nitrogen which is useful to plants is called nitrification.
During the process of nitrification, ammonia or ammonium is first converted to nitrates by the action of the microorganism called nitrosomonas. Nitrobacter converts nitrites to nitrates which are useful to plants.
Hence, the order in which toxic nitrogen compounds are converted to less toxic nitrogen compounds in the nitrogen cycle is NH3 ----> NO2- -----> NO3-
