    this is impossible.... in that case, ther might be the mistake in option (e)... it should be I & III or II & III, but not both.....

    see, if A occurs, B or C occurs and if B or C occurs then, D occurs, so option III is right.... Also when A occurs, D must occur... Suppose if A causes B, then B causes F and D causes G, so option I.... Next if A causes C, then C causes E and D causes H, option II.... As A can cause only B or C so, option I or option II only, but not both...

    Similarly, if B occurs, D, F and G must occur... M not satisfied wid d options given for que 12.....
    J occurs only if E or F occurs.....E occurs if C occurs and F occurs if B occurs.. so, option b..
    Cause is not mentioned for A.. so, A may occur as a result of cause not mentioned but as A must cause D from prev xplanation, so ans is both A and D..
    E occurs when C occurs... that means B cannot occur, as F occurs only if B occur, so ans is F...............
