Ramapithecus → australopithecus → Homo habilis → Homo erectus
Ramapithecus → homo habilis → Australopithecus → Homo erectus
Australopihecus → Homo habilis → Ramapithecus → Homo erectus
As we have already discussed in Origin & Evolution of Man -

Australopithecus was considered being ancestral to all hominids of the genus Homo. and exist about 5 mya
Homo habilis was the makers of stone tools and exists about 2 mya
Homo erectus probably ate meat and exist about 1.5 mya
Hence, the correct option is (b).
