If A > B, B > C and C > D, then which of the following conclusions is definitely wrong?
- a.A > D
- b.A > C
- c.D > A
- d.B > D
Answer: (C) D > A
Chaining the given inequalities gives $A>B>C>D$, meaning A is the greatest and D is the smallest of the four. "D > A" directly contradicts this chain and is therefore definitely wrong, while $A>D$, $A>C$ and $B>D$ all follow validly from the chain.
