Correct answer choice is :
B) Arab Muslims
Explanation:
The Arab incursion of the Maghrib started in 642 AD when Amr ibn al-As, the ruler of Egypt, overran Cyrenaica, pushing as far as the city of Tripoli by 645 AD. Further development into North Africa anticipated another twenty years, due to the First Islamic civil war. In 670 AD, Uqba ibn Nafi al-Fihiri attacked what is now Tunisia in an effort to take the country from the Byzantine Empire, but was only partly strong. He established the town of Kairouan but was renewed by Abul-Muhajir Dinar in 674 AD. Abul-Muhajir strongly developed into what is now northeastern Algeria including the Berber confederation governed by Kusaila into the Islamic field of power.
