    'P*Q' means 'P is neither smaller than nor equal to Q'.
    'P#Q' means 'P is neither greater than nor equal to Q'.

    Answer : Option D

    Explanation :

    H ≤ V -- (i); V = M -- (ii); M > R -- (iii)

    Combining all, we get H â‰¤ V = M > R => no relationship between H and R can be established. Since, conclusion I and II are not exhaustive, neither of them is true.
