(a) Homo habilis	1. 900cc
(b) Homo neanderthalensis	2. 1450cc
(c) Homo erectus	3. 650-800cc
(d) Homo sapiens	4. 1400cc

Choose the correct option.

• A. a-3, b-2, c-1, d-4
• B. a-1, b-4, c-3, d-2
• C. a-3, b-4, c-1, d-2
• D. a-1, b-2, c-3, d-4

Answer 1

The correct option is C a-3, b-4, c-1, d-2

Brain capacity or cranial capacity is the volume of the interior of the cranium of vertebrates which includes the brain. It is used to approximate the size of the brain, which is also suggestive of the intelligence of the organism.

The cranial capacity of the above organisms are as follows:
Homo sapiens - 1450cc
Homo habilis - 650cc to 800cc
Homo neanderthalensis - 1400cc
Homo erectus - 900cc
If we see the evolution of each of the above ancestors we find that at each step brain capacity increases.
