Solution
The correct option is C Greater cranial capacity
Social life and power of speech are not unique characters of man. Several other animals especially, Arthropods lead a social life and power of speech is present in several vertebrates. Superior intelligence does not distinguish man from apes. Apes are also categorised as intelligent animals. However, apes have a lower cranial capacity (100 cc in Gibbon, 400 cc in Orangutan and Chimpanzee and 550 cc in Gorilla), but man has a higher cranial capacity (1400 - 1450 cc). Man also has a higher brain to body weight ratio as compared to apes.So, the correct answer is option D.
