    A Neither conclusion follows Correct Answer Incorrect Answer
    B Both conclusions II and III follows Correct Answer Incorrect Answer
    C Only conclusion III follows Correct Answer Incorrect Answer
    D Both conclusions I and III follows Correct Answer Incorrect Answer

    Solution

    All Z are X (A) + [All G are X (A) → Conversion] → Some X are G (I) → No conclusion. Hence conclusion I is not true. All G are X (A) → Conversion → Some X are G (I). Hence conclusion II is not true. All Z are X (A) → Conversion → Some X are Z (I). Hence conclusion III is true.
