The Group A line-up will be completed by the winners of a preliminary tie involving Namibia, Congo Brazzaville, Libya and Rwanda.
Nigeria can be confident of making the 16-team finals between January 17 and February 8 in Moroccan cities Agadir, Marrakech, Rabat and Tangier.
They are a bogey side for South Africa -- never losing a competitive match to Bafana Bafana (The Boys) -- and Sudan have struggled lately.
Every draw creates a 'group of death' and Group G fits the bill with Tunisia, Egypt, Senegal and one from Burundi, Botswana, Central African Republic and Guinea-Bissau.
Egypt have lifted the Cup of Nations a record seven times, hosts Tunisia triumphed in 2004 and Senegal were the strongest third seeds.
Another mini-league set to generate fierce competition is Group D, which includes Ivory Coast, Cameroon and the Democratic Republic of Congo.
