The sequence of evolution of man or Homo sapiens is 
Dryopethicus and Ramapithecus are primates exist about 15 million years ago
Evidence shows during 2 million years ago Australopithecus probably lived in East African grassland.
Homo habilis considered as first human being like.
Fossils discovered in Java in 1891 revealed the next stage known as 
Homo erectus about 1.5 million years ago with the brain capacity of 900 cc.
The Neanderthal man with the brain size of 1400 cc lived near east and central Asia between 1,00,00 to 40,000 years back.
Cro-Magnon evolved from Neanderthal and are found in Europe known as early modern man.
Homo sapiens arose in Africa and moved across continents between 75,000 to 10,000 years ago and is known as a modern man.
So the correct option is 'Australopithecus, Neanderthal Man, Cro-Magnon Man, Modern Man'.

cleistogamous flowers are bisexual flowers that never open. autogamy takes place in such flowers and they dont require pollinators. these flowers are usally geocarpic that is they grow under the soil . eg viola commelina oxalis
