Step-by-step explanation:
The similarity between the Songhai Empire and the previous empires of Ghana and Mali lies in their significant trade routes. Each of these empires flourished due to their control over the trans-Saharan trade routes, which were vital arteries of commerce in the region; they managed the flow of goods such as gold, cloth, salt, and more.
These routes facilitated not only the economic prosperity but also the cultural exchanges, spreading religions like Islam and fostering learning and scholarship.

Feudal systems, Buddhism, and female monarch ruling were not common traits shared by all three empires, making option 'c' the correct answer to how the Songhai Empire was similar to the Ghanaian and Malian empires.
So option c is correct.
