Prosimians differ from simians in

• A. Having claws instead of nails.
• B. Having claws in some of the digits.
• C. Having shorter hind limbs
• D. Presence of tail

Answer 1

Answer: (B)

Having claws in some of the digits.

• Prosimians include The lemurs, lorises and tarsiers and Simians include The monkeys, apes and man.
  
• Prosimians are primitive primates. They retain claws on some digits, having nails on others. The hindlimbs are longer than forelimbs. The tail may be present or lacking.
  
• Simians have nails on the digits. Forelimbs are longer than the hindlimbs. The tail may or may not occur.
  

So, the correct answer is 'having claws in some of the digits'.
