Only laptop is TV means All TV are laptops and in this case TV will not have any relation to anyone. Hence conclusion I does not follow. Some microwaves are fridges (I) → Probable conclusion → All fridges can be microwaves (A). Hence conclusion II follows. No mobile is microwave (E) + Some microwaves are fridges (I) → Some fridges are not mobiles (O*) + Some laptops are fridges (I) → No conclusion. Hence conclusion III does not follow. Alternate Method -
