Correct Answer - Option 4 : C
From the given statements: A is richer than B, C is richer than A, D is richer than C, E is richest. We conclude:
E > D > C > A > B
So, if they are made to sit in the degree of richest, the arrangement would be : E > D > C > A > B
C will have central position.
Hence, option 4 is the correct answer.
