The correct option is D Remarkable increase in the brain size

The brain capacity gradually increased from early human ancestors. Homo habilis has 650800 c.c. brain capacity which increased around 900 c.c., in Homo erectus. The Neanderthal man had 1400 c.c., brain capacity which evolved to around 1450 c.c., in Homo sapiens sapiens.
So, the correct answer is 'Remarkable increase in the brain size'.
