Select the code that states the conclusion/conclusions drawn validly (taking the premises singularly or jointly). Premises : (a) All bats are mammals. (b) No birds are bats. Conclusions : (i) No birds are mammals. (ii) Some birds are not mammals. (iii) No bats are birds. (iv) All mammals are bats.

conclusions--

1) No birds are mammals यह गलत है क्योंकि ऊपर बताया बताया गया है कि All birds are mammals

2)Some birds are mammal यह भी गलत है क्योंकि All birds are mammals

3)No bats are birds यह बिल्कुल सही है क्योंकि Statement के छवि में Bats or Birds का कोई Connection नहीं है।

4)All mammals are bat यह भी गलत है।
