    C Only I and III follow Correct Answer Incorrect Answer
    D All follow Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    All reactions are actions (A) ⇒ conversion = Some actions are reactions (I) ⇒ possible concl. ⇒All actions may be reactions (A). Hence, I follows. Here, all the given statements are positive statements and conclusion II is a negative conclusion. As we know that no negative define conclusion can be drawn from the positive statement, we can say that conclusion II will not follow. All affects are effects.(A) + All effects are reactions.(A) = All affects are reactions.(A) ⇒ conversion ⇒ Some reactions are affects.(I), Hence, conclusion III does not follow.
