i think answer of question 2 is b because cranial capacity of neanderthal man was 1450 cc and cro-magnon man was 1600 cc and for modern man is 1400 cc.
i think they r confusing us
qki bracket me homosapiens mention kar rahe h acc. to that ans 1 is correct
becoz homo sapiens include-neaderthal man
-cromagnon man
-homo sapiens sapiens
(modern man)
aur agar ham homo sapiens ke ancestors ki bat kare then they have inceasing capacity
and if we ans this ques in acc to modern man then ans 1 will wrong
Hn b ho skta h as that option is also significant bt question m most significant pucha h agr starting s dekhthe for example Australopithecus jiski cranial capacity 500 cc h toh modern man tk badhi hi rhi h or baat kre neanderthal and cromagnon man ki toh humko ye pta hona chahiye ki neanderthal man homo sapiens m evolve nhi hua tha toh us hisaab s dekhenge starting s toh option 1 hi crct h 😊
