Contentious societies are most prone to having which of the following? A broad and equitable distribution of wealth B high levels of support for the justice system C pervasive internal conflict or civil war D weak military leaders but strong diplomats

The question is asking about the characteristics of contentious societies. A contentious society is one that is characterized by conflict, disagreement, and discord. Among the given options, the one that best fits the description of a contentious society is "pervasive internal conflict or civil war". This is because internal conflict or civil war indicates a society that is in a state of constant disagreement and discord, which is a hallmark of a contentious society. The other options, such as a broad and equitable distribution of wealth, high levels of support for the justice system, and weak military leaders but strong diplomats, do not necessarily indicate a contentious society. Therefore, the correct answer is option C.
