Which of the following traditional political systems was segmentary?

The traditional political system that was segmentary is the Igbo political system. In a segmentary system, political power is dispersed among various subgroups or lineages, which form a larger political unit. In the Igbo system, power was decentralized and exercised by a council of elders representing different lineages, with no single ruler or centralized authority. This is in contrast to the other options listed, such as Kanem Bornu, Benin, and Yoruba, which had more centralized forms of government with a single ruler or monarch.
