    A Only conclusion III follows Correct Answer Incorrect Answer
    B Only conclusion I and III follow Correct Answer Incorrect Answer
    C Only conclusion II and III follow Correct Answer Incorrect Answer
    D Only conclusion I, II and III follow Correct Answer Incorrect Answer
    E All of the above conclusions follow Correct Answer Incorrect Answer

    Solution

    Only Turtle is Dog → All Dog is Turtle and Dog cannot have positive relation with anyone. Hence conclusion I follows. No Cat is Camel (E) + [ All Parrot is Camel (A) → Conversion] → Some Camel is Parrot (I) → Some Parrot is not Cat (O*). Hence conclusion II follows. Some Turtle is Cat (I) + No Cat is Camel (E) → Some Turtle is not Camel (O) → Probable conclusion → All Camel can be Turtle (A). Hence conclusion III follows but conclusion IV does not follow.
