The right answer "Indigenous"
North Africa has a Muslim majority for several centuries, yet sub-Saharan Africa has experienced a dramatic religious shift in the 20th century. In 1900, Christians (9%) and Muslims (14%) were a minority in sub-Saharan Africa, while 76% of the population followed African indigenous religions. Many of these religions were brought to the Americas through the slave trade and gave birth to African-American religions, such as candomblé and umbanda in Brazil, santeria in Cuba and voodoo in Haiti.
