Cameroon secured their progress with a 1-0 victory over Group I rivals Libya on Sunday, with Aurelien Chedjou’s first international goal in the 42nd minute enough to keep his side top.
Cape Verde, meanwhile, beat Tunisia 2-0 to progress at their opponent's expense in a stunning result. Platini opened the scoring for Cape Verde in the 28th minute, before Ramos Nhuck doubled the advantage three minutes before half-time.
Meanwhile, Senegal did enough to progress after defeating Group J rivals Uganda 1-0.
A win for Uganda would have seen them qualify ahead of their rivals, but they faced an uphill struggle when Godfrey Walusimbi was shown a straight red card in the 36th minute. The winner came courtesy of Sadio Mane six minutes from time as Senegal made it safely through.
Ethiopia's passage was less assured as they had to come from behind against Central African Republic to seal their place in the final round.
Les Fauves went ahead through Salif Keita midway through the first 45 minutes, but second-half strikes from Saladin Said Ahmed and Menyahel Teshome ensured Ethiopia's progress.
Nigeria were another side to seal their passage into the final round as they defeated 10-man Malawi 2-0.
A win for Malawi would have seen them qualify, but an Emmanuel Emenike goal in first-half stoppage time and a Victor Moses penalty on 51 minutes saw the Super Eagles through.
South Africa, Tunisia, Morocco and Mali were amongst the major sides to miss out on progression during the second stage of the qualification process, ending their hopes of a ticket to Brazil.
The 10 teams to progress are now one step away from a place in the World Cup next summer, with five two-legged play-off matches, taking place in October and November, deciding Africa’s final qualifiers for the tournament.
