          Answer & Explanation
         Answer: B) D         
         
Explanation: A > C  -----(i),   B > D  -----(ii),  E < B  --------(iii),  E > C  ---------(iv),  C > D  ---------(v)
from (i) and (v),   we get    A > C > D   ---------(I)
from (iii) and (iv), we get    B > E > C    --------(II)
From (I) and (II) , it is clear that 'D' is the thinnest.
